Dan.The.King's AI fitting help

[Dan.The.King]

I enjoyed @PeRiCo 's thread, so I decided to throw all of my data from my last 100 shot sim session into ChatGPT to see what it says. In that session I was testing ProV1 against CTTD, but then also asked about if there is anything I should change with my clubs.

1. 7-iron benchmarks vs your data (reality check)​

For an 86 mph 7-iron, ideal windows (TrackMan / GCQuad ranges):

Metric	Ideal	You (Pro V1 avg)
Ball speed	118–120	109
Carry	158–165	152
Spin	4500–5000	5130
Peak height	80–95 ft	86 ft
Descent angle	45–50°	45.2°

Key takeaway:
Your height and land angle are excellent, but you’re giving up ~6–10 yards of carry due to:

• Excess spin
• Excess dynamic loft
• Inconsistent strike efficiency

This is not a “swing is bad” problem — it’s delivery + equipment mismatch.

---

2. Lie angle: 2° upright — helping, but not fixing the right miss​

Even at 2° upright, you still show:

• Club path: +5.5°
• Face-to-path: +1.8° avg
• Side total: ~76 ft right

That tells us something important:


The right miss is not lie-angle driven anymore.
It’s face timing + shaft profile, not turf interaction.


So:

• No more upright bending
• No flatter either
• Lie angle is basically “done”

---

3. Shaft: now that lie is ruled out, this is the smoking gun​

What the KBS Tour Lite S is doing to you​

• Adds dynamic loft (~25°)
• Increases spin loft (~27°)
• Slows face closure for your strong in-to-out path
• Increases dispersion when you go after one

This is classic high-path + lighter / softer shaft behavior.

Why this matters at 86 mph​

You’re right at the speed where:

• Lighter ≠ more speed
• Heavier ≠ slower

In fact, many players at your speed gain ball speed with a more stable shaft.

---

4. Shaft profiles that now make the MOST sense​

Given:

• 2° upright
• Persistent right bias
• Excess spin
• 7-iron speed 86 mph

Best-fit profiles (ranked)​

Project X 5.5​

• Lowest spin loft of the group
• Reduces right miss
• Tightens face-to-path
• Often adds 2–4 mph ball speed for players like you

Dynamic Gold 105 S300​

• Excellent mid-launch, controlled spin
• Better face stability than KBS Tour Lite
• Keeps your height but improves carry

Nippon Modus 105 S​

• Slightly higher launch than DG 105
• Still much better than Tour Lite
• Good feel if you’re tempo-driven

I would not recommend:

• Staying in Tour Lite
• Going lighter than 105g
• “High launch” labels

---

5. Ball fit — now even clearer​

Why both balls are wrong for this 7-iron delivery​

Pro V1​

• Borderline acceptable
• Still spins too much for your delivered loft

Chrome Tour Triple Diamond​

• Flat-out too spinny
• Costs you ~9 yards carry
• Exaggerates curvature with your face/path relationship

Best balls for YOUR iron delivery​

Top tier fits​

• Titleist AVX
• Bridgestone Tour B RX
• Srixon Q-Star Tour

“Tour ball but lower spin” options​

• Pro V1x Left Dash
• TaylorMade TP5x (not TP5)

Expect with the right ball alone:

• Spin drop: 400–700 rpm
• Carry gain: 4–6 yards
• Straighter flight

---

6. Grip size note (small but real effect)​

You’re in:

• Midsize
• Lamkin Crossline (firm, low torque)

For a player who:

• Delivers face open
• Has a strong in-to-out path

This can slow face closure just enough to matter.

I would test (before changing swing):​

• Same grip
• +2 wraps lower hand only
• Keep upper hand unchanged

This often reduces face-to-path ~0.5–1° without killing feel.

---

7. What “optimized” would look like for you​

With:

• Better-fit shaft
• Lower-spin ball
• Same head / lie

Target averages:

• Ball speed: 114–116
• Carry: 158–162
• Spin: 4600–4800
• Peak height: 80–88 ft
• Side total: <40 ft

That’s a full club improvement without touching mechanics.

---

8. Bottom line (clean and direct)​

• 7-iron numbers confirm you should hit it farther
• Lie angle is correct at 2° upright
• KBS Tour Lite S is holding you back
• Chrome Tour TD is the worst ball fit
• Pro V1 is playable but sub-optimal
• Best gains = shaft + ball combo

 

[kiwichris]

Man, that is really eye opening how well it is identifying things and providing fixes.

I need to get some data like this and see what it comes up with.

 

[E.Appleton]

Is it just me or is 4500-5000 rpm for a 7i seem low? This is really cool though

 

[Mayor McCheese]

This is super interesting! I wonder if I’m an old man now, because I would have slight reservations about doing this for myself when I’m not fully knowledgeable enough to know if the recommendations are accurate. Maybe that’s why posting it on THP is helpful?

 

[OldandStiff]

Intelligence becomes a more interesting word every day.

 

[The Milk Man]

Are you right or left handed and what is your face angle at impact?

 

[Dan.The.King]

Is it just me or is 4500-5000 rpm for a 7i seem low? This is really cool though

I thought the same thing, but I know we're not at the iron x 1000 rpm anymore.

This is so cool I will follow. CT gave me the same results — a real eye-opener. Same with shafts. Really interesting stuff.

 

[Dan.The.King]

Are you right or left handed and what is your face angle at impact?

I'm right handed and average face angle was 7.4 +/- 4*, so not consistent at all.

 

[E.Appleton]

I thought the same thing, but I know we're not at the iron x 1000 rpm anymore.

Definitely true, but that still seems a little low. Descent angle looks fine, but I would disagree with going to anything lower spin and in fact would want the opposite. That being said I am just an ignorant hacker enthusiast and would defer to more knowledgeable people here.

 

[Dan.The.King]

This is super interesting! I wonder if I’m an old man now, because I would have slight reservations about doing this for myself when I’m not fully knowledgeable enough to know if the recommendations are accurate. Maybe that’s why posting it on THP is helpful?

Oh be quiet you're younger than me.

I'm not taking these recommendations as gospel. I think it's pointing in the right direction though. For example on the shaft: when I was demoing the AI150s the fitter put me in a heavier shaft and I was seeing better flight and dispersion than with the Tour Lite.

 

[AuzzieMatt]

Can I ask how you go about putting the sim data into AI? Do you export it to your PC then just paste it in?

I'm interested on what it would say for me but have no idea how to do it.

 

[Dan.The.King]

Can I ask how you go about putting the sim data into AI? Do you export it to your PC then just paste it in?

I'm interested on what it would say for me but have no idea how to do it.

I copied all of the data from the Trackman report into an excel sheet. You can either attach the document or copy and paste all the data into the prompt. I started with this prompt: "I was golf ball testing, but it seems that neither ball is optimal for my current set up. I'm also trying to figure out if my current iron set up is the best for me." I did give it the club, shaft, grip, and loft/lie information.

 

[Dan.The.King]

I decided to use Chatgpt again by putting in the handful of shots I took with the OPTM X the other day. I asked it which head would be the best for me from the OPTM and Quantum lines.

Your Driver DNA (from the OPTM X data)​

Averages (A1 + B4 combined trend):

• Club Speed: 102–104 mph
• Attack Angle: +3.5°
• Club Path: +5–6° (in-to-out)
• Dynamic Loft: ~17°
• Launch: ~15–16°
• Spin: 2800–3000 rpm
• Strike: center / high-toe
• Miss: push or push-fade

You are launching and spinning it like a 10.5° MAX head player, not like a low-spin player with upward AoA.

---

Best Cobra OPTM Driver for You (2026)​

Cobra OPTM LS — 9.0°​

(Not OPTM X, not MAX)

Why this is the correct OPTM head​

• OPTM X adds dynamic loft and MOI → exactly what your data says you do not need
• OPTM LS moves CG forward and slightly lowers face
• Neutral face works with your +5° path instead of fighting it

Recommended Cobra OPTM build​

• Head: OPTM LS
• Loft: 9.0°
• Hosel: Start Neutral, test -0.5°
• Weight: Heavy forward
• Shaft:
  • Kai’la Dark Waves Black 60S (works)
  • Ventus Black / TR Black (if dispersion > speed)

Expected vs your OPTM X​

Metric	OPTM X	OPTM LS
Launch	15–16°	12–13°
Spin	2800–3000	2100–2400
Carry	243–245	258–265
Total	255–260	275–285

---

Best Callaway Quantum Driver for You (2026)​

Callaway Quantum Triple Diamond — 9.0°​

(This is the direct TD successor in the Quantum line)

Why Quantum TD fits you best overall​

• Most neutral/open face in the Quantum family
• Forward CG controls spin without killing launch
• Better at handling in-to-out path + toe strike
• Historically Callaway TD heads are outstanding for players like you

Recommended Quantum build​

• Head: Quantum Triple Diamond
• Loft: 9.0°
• Hosel: -1° (opens face slightly)
• CG: Forward
• Shaft:
  • Ventus Black / Black TR
  • Project X LS
  • Denali Black

Expected improvement​

• Spin ↓ 700–900 rpm
• Smash closer to 1.50
• Miss tightens from push-fade → gentle baby fade
• Best scoring driver

---

Cobra OPTM LS vs Callaway Quantum TD (for YOU)​

Category	Winner
Ball speed potential	Cobra OPTM LS
Spin control	Tie
Face angle neutrality	Quantum TD
Dispersion	Quantum TD
Forgiveness at speed	Cobra OPTM LS
Overall fit	Quantum TD

If you told me:

“Build one driver strictly off this TrackMan session”

I’d build:

Callaway Quantum Triple Diamond, 9.0°, -1° hosel, Ventus Black 6S

---

One final, very important note​

Your 10.5° OPTM X head is masking your efficiency.
Nothing in your data suggests you need:

• added loft
• rear CG
• draw bias

Once you move to LS / TD, your numbers should immediately normalize.

 

[Dan.The.King]

I'm not necessarily surprised by the LS recommendations as that's what I currently play, but I did want to know why not the TD Max, because if I blind apply for the Quantum testing that's where I was probably going to go.

Great question — and this is exactly the right follow-up given your data.


Short answer first:

Quantum Triple Diamond Max is good, but it solves problems you do not have — and it introduces one you already do.

Now let’s walk through it using your OPTM X numbers, not theory.

---

1. What “TD Max” actually changes vs TD​

In the Quantum line:

Head	What changes
Triple Diamond (TD)	Forward CG, neutral/open face, compact
Triple Diamond Max (TD Max)	CG pulled back, slightly higher MOI, a touch more dynamic loft

TD Max is not just more forgiving — it raises spin and launch relative to TD.

---

2. Your data says you do NOT need what TD Max gives​

From your OPTM X averages:

• Dynamic Loft: ~17° already too high
• Launch: 15–16° already too high
• Spin: 2800–3000 rpm already too high
• Attack Angle: +3.5° good
• Strike: center / high-toe good

TD Max would:

• Add ~1° dynamic loft
• Add ~200–350 rpm spin
• Slightly close the face at impact

That moves you away from optimal, not toward it.

---

3. The big one: your path + TD Max = left-side risk​

Your club path is +5 to +6° consistently.


TD Max characteristics:

• More face closure rate
• More gear effect stability (less face deflection)

That combination with your path increases:

• Start line left
• Over-draws when timing is good
• Two-way miss (your worst-case scenario)

TD (non-Max) keeps the face:

• More neutral/open
• Slower closure rate
• Better aligned with your delivery

---

4. Dispersion: where TD Max actually loses to TD for you​

Yes, TD Max is more forgiving in isolation.


But for your swing:

• Forgiveness = keeping spin & face stable
• TD already does that at your strike quality
• TD Max adds stability you don’t need → launch/spin creep

Your OPTM X data already shows:

• Side total controlled
• Miss comes from spin & loft, not strike inconsistency

So TD Max tightens bad strikes you rarely hit, and worsens average strikes, which you hit most often.

---

5. When TD Max would be the right call​

TD Max makes sense if you had:

• Spin < 2200 rpm
• Launch < 11°
• Strike low-heel
• Path near 0°
• Club speed < 98 mph

You are the opposite of that player.

---

6. Head-to-head summary (for YOU)​

Metric	TD	TD Max
Launch	Lower	Higher
Spin	Lower	Higher
Face neutrality	Better	Slightly closed
Dispersion	Tighter	⚠ Two-way risk
Yardage	More	Less

---

Bottom line​

Quantum Triple Diamond Max is a great head — just not for your delivery.

With your:

• +5–6° path
• +3–4° AoA
• High dynamic loft

You want:

Less head help, not more.

That’s why Quantum Triple Diamond (standard) remains the best fit for you.


If you want, we can still test TD Max as a control — but I’d expect:

• +200–300 rpm spin
• +1° launch
• Slightly worse scoring dispersion

If that’s worth validating for peace of mind, I’ll tell you exactly how to test it properly on TrackMan.

I did ask it for a testing routine, but didn't think it was quite relevant to what I'm trying to show here.

 

[Dan.The.King]

I'm going down a rabbit hole here. I asked it why the TD is better even though OPTM has the FF33 adapter.

Short answer up front:

Yes — the FF33 hosel can give the Cobra OPTM LS a tuning advantage over OptiFit4, but it does NOT change the core head fit advantage that Quantum TD has for your swing.

Let’s unpack that carefully, because the nuance matters.

---

1. What FF33 actually does (and what it doesn’t)​

Cobra FF33 hosel​

• Allows face angle, loft, and lie to be manipulated more independently
• Lets you:
  • Open the face without adding loft
  • Flatten lie without closing the face
• Extremely useful for players with:
  • Positive path
  • Left-miss sensitivity

This is better adjustability than OptiFit4 — no question.

---

Callaway OptiFit4 hosel​

• Loft and face angle are still somewhat linked
• Less granular, but:
  • Triple Diamond starts more neutral/open to begin with
  • Needs less adjustment for your delivery

OptiFit4 is simpler because the head already suits you.

---

2. Why FF33 helps Cobra — but doesn’t flip the verdict​

Your key issues from TrackMan:

• Dynamic loft too high
• Spin too high
• Path +5–6°
• Face slightly open relative to path

FF33 can:

• Open the face a touch → reduce left risk
• Flatten lie → reduce face closure
• Slightly reduce delivered loft

But FF33 cannot move CG.


And CG location is the primary driver of:

• Spin
• Launch stability
• Strike response

---

3. CG vs hosel: which matters more for you?​

For your specific delivery:

Influence	Importance
CG forward/back
Face angle bias
Lie angle
Hosel adjustability

Quantum TD’s forward CG + open face already puts you in the right window before adjustment.


Cobra OPTM LS needs FF33 to:

• Counteract a slightly higher inherent launch
• Neutralize face closure

So FF33 is doing more work on the Cobra.

---

4. Where FF33 does give Cobra a real edge​

There are scenarios where FF33 could swing it:

If:​

• TD still launches >14° at 9°
• Or face-to-path stays positive even at -1°
• Or you want to flatten lie more than OptiFit allows

Then:

• OPTM LS + FF33 (open face, flatter lie, forward weight)
• Could match or slightly beat TD on dispersion

But that’s a narrow band.

---

5. Practical comparison for you​

Cobra OPTM LS (with FF33 dialed)​

Pros

• Excellent face control tuning
• Potentially lower spin if strike moves higher
• Slightly more ball speed upside

Cons

• Still wants to launch a touch higher
• CG not quite as forward as TD
• Needs perfect setup to stay out of left

---

Callaway Quantum TD (minimal adjustment)​

Pros

• Correct CG for you out of the box
• Naturally neutral face with your path
• Less dynamic loft delivered
• More “set it and trust it”

Cons

• Hosel less granular
• Slightly less tweakability if your swing changes

---

6. Bottom-line answer (no hedging)​

FF33 makes Cobra OPTM LS more competitive, not better, than Quantum TD for your swing.

If you enjoy tinkering and dialing:

• Cobra OPTM LS + FF33 is a legitimate option

If you want:

• Best average numbers
• Least setup sensitivity
• Best scoring dispersion

Quantum TD still wins for you.

---

7. How to prove this on TrackMan (simple check)​

When you test:

1. Set OPTM LS with FF33 open + flatter
2. Set Quantum TD at -1°
3. Hit 8–10 alternating shots

If Cobra:

• Matches spin AND
• Matches face-to-path AND
• Matches dispersion

Then Cobra becomes a coin flip.


If not, the data will show why CG > hosel.

More updates to this thread are coming. I did an iron fitting at GG today. I hit my gamer (Sub70 659CB), Titleist T150, Mizuno M15, Maxfli XC2, Srixon Zxi5, and the Apex AI150s. I'll be plugging the data into ChatGPT tonight. I'm interested in what it says because what I would choose right now probably isn't the best from the data.

I'll be plugging the data into ChatGPT tonight. I'm interested in what it says because what I would choose right now probably isn't the best from the data.

What did you like the best before you give us the AI spit out?

 

[Dan.The.King]

What did you like the best before you give us the AI spit out?

The M15s are the leader in the club house based on feel and simulated ball flight. They were the only ones I was able to try out with a 105g graphite shaft, so that probably has something to do with it.

 

[Dan.The.King]

I put the data from my fitting today into ChatGPT for some analysis. Here's the first:

What you tested (7-iron)​

From the file, you hit:

1. Mizuno Pro 225 (listed as M15)
   • Shaft: Mitsubishi MMT 105 Stiff
2. Callaway Apex AI150
   • Shaft: MMT 125 Stiff
3. Titleist T150
   • Shaft: MMT 85 Stiff
4. Srixon ZX5
   • Shaft: Nippon Modus 120 Stiff
5. Sub 70 659 CB
   • Shaft: KBS Tour Lite Stiff

Your 7-iron club speed ~82–84 mph, which is a very important anchor point.

---

Big picture: what that speed tells me​

At ~83 mph with a 7-iron:

• You are solidly in stiff flex
• Ideal shaft weight range is 105–120g
• 85g shafts are almost always too light for consistency
• You’ll benefit from:
  • Mid launch
  • Controlled spin
  • Heavier feel to keep face + path stable

That alone lets us eliminate or downgrade some options.

---

Head + shaft combos that make the most sense​

Top Tier Fits​

Callaway Apex AI150 + MMT 125 Stiff​

This is the sneaky best combo in your session.


Why:

• Head is forgiving without ballooning
• 125g MMT keeps your tempo in check
• Heavier shaft = tighter face control
• Excellent for someone whose miss can be spinny or directional

If dispersion mattered more than raw carry, this is a strong favorite.

---

Srixon ZX5 + Modus 120 Stiff​

Classic fitter’s choice — for good reason.


Why:

• ZX5 launches easy but doesn’t over-spin
• Modus 120 is money at your speed
• Great blend of:
  • Feel
  • Height
  • Front-to-back control

If you liked the feel of this one, it’s absolutely a “buy with confidence” setup.

---

Good, but with caveats​

Mizuno Pro 225 + MMT 105​

• Head: fantastic
• Shaft: borderline light for you

If you loved the Mizuno feel:

• Same head with MMT 125, Modus 120, or DG Mid 120 would likely be better
• 105g may cost you consistency on longer irons

Head = yes. Shaft = I’d go heavier.

---

Least ideal fit​

Titleist T150 + MMT 85​

This one stands out — and not in a good way.


Why:

• 85g is very light for your speed
• Can inflate:
  • Launch
  • Spin
  • Left/right misses
• Often feels “hot” but inconsistent

If this flew far but scattered, the shaft is the reason — not the head.

---

My short list recommendation​

If you forced me to rank best setups for YOU:

1. Apex AI150 + MMT 125 Stiff
2. Srixon ZX5 + Modus 120 Stiff
3. Mizuno Pro 225 + heavier shaft
4. Sub70 659 CB (good value, slightly less refined)
5. Titleist T150 (shaft mismatch)

---

Want me to go deeper?​

I can:

• Clean the file
• Compute averages per club
• Rank by:
  • Dispersion
  • Peak height
  • Landing angle
  • Spin consistency
• Recommend final spec tweaks (lie, length, grip)

This was interesting. I liked the Ai150, but I did not think it would be the top choice. According to the averages and consistency the Ai150s were the second longest carry and 2nd worst carry dispersion. Kind of going against what AI is recommending, but let's see where this leads.

 

[Dan.The.King]

I told it tight dispersion was most important to me.

Best setup for tight dispersion (from what you tested)​

#1 — Callaway Apex AI150 + MMT 125 Stiff​

This is your winner for dispersion. Full stop.
Why this combo works for you:

• 125g shaft stabilizes face delivery at your ~83 mph 7i speed
• MMT profile is smooth but doesn’t kick unpredictably
• AI150 head:
  • Compact enough to reduce gear-effect misses
  • Forgiving enough to protect heel/toe strikes
• Typically produces:
  • Slightly lower launch
  • Controlled spin
  • Narrow left/right window

If dispersion is king, this is the safest gamer from the fitting.

---

Runner-up (very close)​

Srixon ZX5 + Nippon Modus 120 Stiff​

This is the “metronome” setup.
Why it’s so good:

• Modus 120 is one of the tightest-dispersion steel shafts ever made
• ZX5 head keeps ball speed up on mishits without spraying
• Excellent front-to-back consistency, not just left/right

If this felt “boring but good,” that’s actually a huge compliment.

---

What likely hurt dispersion in the others​

MMT 85 (Titleist T150)​

• Too light → timing variability
• Increases closure rate → left/right misses
• Often looks great on single swings, bad over 10 balls

MMT 105 (Mizuno 225)​

• Not terrible, but:
  • More face rotation than 120–125g
  • Slightly wider pattern over a full session

---

How to tighten dispersion even more (important)​

If you want to maximize dispersion control, here are two better-than-stock tweaks I’d strongly consider:

Shaft tweaks (biggest gain)​

If staying graphite:

• MMT 125 Stiff (best graphite choice you hit)

If open to steel (often tighter):

• Modus 120 Stiff
• Dynamic Gold Mid 120
• Project X 6.0 (only if you liked a firmer feel)

These all reduce face deflection and dynamic loft variability — dispersion killers.

---

Lie angle (often overlooked)​

With your swing profile:

• 1° flat is very often the dispersion unlock
• Especially if your miss pattern includes:
  • Pulls / pull-fades
  • Left misses when you “step on one”

This alone can shrink your left-right window by 20–30%.

---

My “tour van” recommendation​

If I were building this for you with dispersion as the #1 KPI:

Callaway Apex AI150
MMT 125 Stiff (or Modus 120 if steel)
Standard length
1° flat
Mid-size grip (or +2 wraps if borderline)

---

One last check (quick but important)​

When you missed during the fitting, which happened more often?

• Left
• Right
• Mostly short/long

That answer lets me lock in lie + shaft profile with zero guesswork.

Again, dispersion was better with the MMT 105, so I'm not sure where it's going. Also, my main miss is a push right, which I told it after this, so I know going flat is not a good idea.

 

[Dan.The.King]

So after telling it my main miss it came up with this:

That’s actually great info — a push-right miss is one of the easiest things to clean up without giving up dispersion. And it confirms a couple of things I was already leaning toward.


Let’s dial this in.

---

What a push-right tells us (with irons)​

A push (starts right, stays right) usually means:

• Face is open to target
• Path is relatively neutral (not a big wipe)
• You’re not flipping — you’re just arriving a hair late

Importantly:
This is not a bad swing problem. It’s almost always fit-related at your speed.

---

How this affects your iron fit (key adjustments)​

Lie angle: do NOT go flat​

Earlier I mentioned 1° flat as a common dispersion fix — for left misses.


For you:

• Flat would make pushes worse
• We want the toe slightly more down at impact

Correct direction:​

Standard → +0.5° or +1° upright


This helps the face return more square without forcing a swing change.

Many players with push-right misses see instant tightening just from +1° upright.

---

Shaft choice: heavier is still correct​

Your push is not because the shaft is too stiff.


In fact:

• Too-light shafts often cause both right and left misses
• Heavier shafts slow down closure consistently, not excessively

So we keep:

• MMT 125
• Modus 120
• DG Mid 120

These promote repeatability, which is what you want.

---

Re-ranking your best setups for YOUR miss​

Apex AI150 + MMT 125 Stiff (+1° upright)​

This is now an even clearer #1.


Why it works for a push miss:

• AI150 has a touch more face stability
• Heavier MMT keeps timing consistent
• Upright lie helps start line without adding hook bias

---

Srixon ZX5 + Modus 120 (+1° upright)​

If you like steel feel, this is still elite.


Srixon heads respond really well to lie adjustments — big win for fitters.

---

Mizuno Pro 225 (but change shaft)​

If you loved Mizuno feel:

• Keep the head
• Move to:
  • Modus 120
  • MMT 125
  • DG Mid 120
• And go +1° upright

---

What I would not do​

Go lighter than 105g
Go flat
Chase more draw-biased heads
Add “help” with offset — that hurts dispersion long-term

---

Final “build sheet” recommendation​

If dispersion is the only KPI and your miss is push-right:


Callaway Apex AI150
MMT 125 Stiff
Standard length
+1° upright
Grip: whatever keeps hands neutral (likely midsize or +2 wraps)


That setup:

• Squares start line
• Keeps left side protected
• Produces the tightest shot cone over time

Ok. It's time to call the AI out. I'm looking for distance dispersion to be tighter, and this just isn't jiving with what it's recommending.

I love that last sentence of the last post because I hate a lot what's in here. My nightmares about people using ChatGPT to decide these things were not helped by this thread. Lol

 

[Dan.The.King]

After telling the AI that the Ai150s had the second worst distance dispersion it retooled itself a little

First: define “tight dispersion” correctly​

There are two different dispersions, and mixing them up causes bad recommendations:

1. Lateral dispersion (left/right)
2. Distance dispersion (front/back)

You told me:

• Priority = tight dispersion
• Reality = AI150 had poor front-to-back control

That means the AI150 fails your #1 requirement, even if left/right looked good.


So: AI150 is out as a top choice.

---

Why the AI150 likely had poor distance control for you​

This isn’t random.


Common causes with AI150 at your speed:

• Face design is hot across a wide area
• Slight strike variance → ball speed jumps
• Paired with MMT 125, you likely got:
  • Stable start line
  • Inconsistent spin retention
  • “Flyers” relative to your average

That produces exactly what you saw:

Tight-ish laterally, but spread out long/short

For dispersion purists, that’s a deal-breaker.

---

So… what actually is the best choice?​

Based on everything now clarified:

Srixon ZX5 + Modus 120 Stiff​

This is now your clear #1.


Why this one rises to the top:

• Modus 120 = elite spin consistency
• ZX5 face = forgiving without jumpers
• Very stable peak height and landing angle
• Typically the tightest front-to-back window in fittings

This combo is famous for being “boring” — and boring equals repeatable.

---

Second best (conditional)​

Mizuno Pro 225 — but NOT with MMT 105​

The head itself is excellent for distance control.


To tighten dispersion:

• Swap to:
  • Modus 120
  • DG Mid 120
  • MMT 125
• Keep lofts traditional (don’t strengthen)

With the right shaft, this could rival the ZX5.

---

Clubs I would deprioritize for your goal​

• AI150 → too much ball speed variance
• T150 with MMT 85 → unstable strike + spin
• Ultra-forgiving, thin-face irons → bad for distance gapping

---

Final corrected ranking (for YOU)​

1. ZX5 + Modus 120
2. Mizuno Pro 225 + heavier shaft
3. Sub70 659 CB (good value, decent control)
4. AI150 (fails distance dispersion test)
5. T150 (shaft mismatch)

This matches the data better and is more what I'm looking for. For clarity the ZX5s had the best carry consistency at 161.8 +- 8.2 yards and an OK landing angle. They didn't necessarily feel the best, but I'll try them again. Also, the MMT 125s would be a full custom order for either of the irons because they aren't offered even as an upcharge.

Some of it could be the prompt, but it does seem to be looking at one data point and running with it instead of looking at all of it together. Mostly I'm using this to narrow down options but I'm not sure how much I can trust it right now. Going off feel I'd like to try the Mizunos, the Ai150s, and ZXi5s against the Cobra 3DP Tours and maybe some others.

The other funny part about the fitting today was the fitter remarking that every time he handed me a club with a wider sole I couldn't do anything but fat it. He had me try the T250* and it went so bad we agreed to just delete the data.
