Probably just the regular spin degradation I normally see indoors, but spin on good strikes is up about 500-1K, which is a huge improvement from the last gen. Peak height is much more consistent, especially in the longer irons - they launch for me much easier than the previous model. Distances are comparable, tough to talk about sole design indoors, especially off thicker mats, but at home on my Fiberbuilt they seem to get through the “turf” without dragging a whole lot.
That is set make up i am looking at.
I'll see what 2026 does, but I love hearing the improved numbers on the irons. Definite ponder on upgrading next year, and given better long iron shots this year, I'm curious about how the new long irons would behave in my hands.
Yeah, that upright fitting had me questioning my swing for a minute I genuinely thought I forgot how to strike a ball. Once I got back to my usual lie angle, contact and spin came right back. Sanity restored.
I am going to agree that the T100/150 are both firm coming from Srixon zx7/zxi7s. BUT, I have yet to touch an iron that comes remotely close to them so that’s also a matter in its own.
Interesting I haven't seen anyone talk about this so I definitely appreciate the feedback. As you know they are fantastic irons and I love the look of them so I guess I'll work on my striking some more lol. I use about a nickel sized spot on the face leaning toe side so I'm not quite dime sized perfect.
I only have experience with steel shafts but yeah, the Srixons are really soft across the entire face so even on just OK strikes, they still feel good. The T100/150s feel great on good strikes but will let you know where you stuck the ball on the clubface which some might like or not. I think somebody coming from Mizuno or Srixon will notice this more than anybody else.
Amazing write up! One thing I've noticed with the T150s and the T100s in the longs is the apex stays high and it's incredible to see.Monday marks 3 months since we all received our T-Series irons at the wonderful ArborLinks. I have somewhere around 50+ rounds on mine with many hours of range time, so they’ve definitely been worked! I am out of town this weekend so posting this a few days early.
As a reminder, my setup is PW–5i T-150s bent 1° weak with Stiff Project X LZ shafts and Z-Cord grips. I typically bounce between the Pro V1x and the Callaway Chrome Tour Triple Diamond (I know… vastly different balls).
Wear
The T-150s are holding up very well! Central Texas is very firm with often times rock playing a part in course obstructions and construction. These clubs have not taken any damage from those conditions unlike other irons I have which nicked very easily. Club face is showing some wear from play and range time but it is natural and not in excess. Being transparent, I did have to send the 5 iron in for replacement as a piece inside the head came loose and was making a high pitch “ting” on shots. Titleist replaced it no questions asked!
Forgiveness
Coming from Srixon ZX7/ZXi7 irons, there is a noticeable improvement in forgiveness with the T-150s. I’ve found that toe and thin strikes are usually only a handful of yards short. Obviously, max height on a thin shot is going to be lower, but it still produces a very playable ball flight with solid distance. It’s honestly remarkable how well these irons handle a thin miss. I’ve saved many holes from bogey or worse thanks to the forgiveness. Huge props to the team at Titleist!
Distance, Descent, Dispersion
Spin and height are beyond amazing. As a naturally lower-spin iron player, I’ve always needed a higher-spinning ball to get my numbers where I want them. I like seeing my shots climb and then drop. I don’t care what club I need to hit to get a distance; I just want the ball to stop where it lands unless I choose otherwise.
With the T-150s being 1° weak and the LZ shafts, I have zero issues getting any ball in the air or stopping it. The ball launches, climbs to its apex, and then drops and stops. Apex windows are consistent throughout the bag. My 5-iron from 200 yards will stick on receptive greens or roll out just a few feet if it’s firm. Anything 7-iron and below will hold about 95% of the time unless I purposely take spin off for rollout. I even spun back a 9-iron on bent greens in the middle of August in Texas from 155 yards.
Height is in a window I absolutely love. I can sling it way up or flight it low.
Punch shots require a bit more focus to keep the launch down. I’m guessing that’s because of the shaft launch and the slightly weaker lofts on the 150s compared to my ZXi7s with $-Tapers but I’m not complaining!
Left-right dispersion is the tightest it has ever been. I know I’ve said it before, but I’ll say it again: these are point and shoot for me. I’ve worked hard to get a very neutral swing path, and these irons definitely reward that with solid strikes.
Distance is very repeatable. If I want to draw the ball, it hits the number and draws in. If I want to cut it, I typically see about a 10-yard loss and a bit more spin. It’s a fun shot to hit and feels great, but I don’t like seeing the ball move left-to-right, so I don’t hit it often.
If I had to choose one word for the T-150s, it would be consistent.
Feel / Sound
Feel and sound are obviously subjective from golfer to golfer. That’s the entire point behind Titleist’s “Finding Feel” and why it is such a hard thing to accomplish.
Some prefer a firm iron; others prefer a soft one. I personally prefer a soft and buttery feel coming from four years of Srixon ZX7/ZXi7s and Callaway Apex irons before that.
In my opinion, the T-150s are firmer than a forged Srixon or Mizuno but very consistent compared to other irons in their category from brands like TaylorMade and Callaway. Compared to the prior generation of T-150s, these definitely feel and sound better!
With the current generation, if you strike it right in the center, it’s a soft, buttery feeling similar to my Srixon’s. Almost as if the ball wasn’t there. If you’re slightly off-center, the T-150s with let you know. I don’t see this as a bad thing; it’s just slightly firmer outside of the sweet spot. Just a bit more “dense” feel. It took me about a week to get acquainted with it, but now I truly love the feedback. What you feel is exactly what the shot was. Thin is thin, Toe-y is toe-y, and a shank is a shank!
This feedback has grown my ball-striking immensely. My main miss is not holding my wrist angles through impact which causes a thin or thin-feeling shot. Thankfully, the forgiveness (as mentioned above) saves the shot and the feedback helps me adjust and correct my swing.
Now, for the 5, 6, and 7 irons with the Muscle Channel, you can feel it. Primarily on misses but still there on every shot. The feel is similar to the short irons but with a slightly more cavity-like sensation. It doesn’t bother me at all and actually amplifies the sensation of the ball launching off the face. Each time I pull a long iron out and crush one, I am wowed! Such a great feeling! I would say my 5 and 6 irons are my favorite clubs in the bag.
Sound-wise, the T-150s have a nice “schwack” followed by the whooshing ball sound. They’re decently loud for a forged iron but again, I personally like it.
Overall
The past 3 months have been nothing short of a blast with the T-150s. My handicap before getting them was floating around a 12. I currently sit around an 8 and dropping each round. I shot my first bogey-free front nine on my home course, consistently shooting in the 70s, and truly enjoy every iron shot I hit. I’d attribute a large portion of the improvement in my game to these irons (along with finding my driver swing after it decided to take a vacation). I’m looking forward to the next 3 months with a goal of getting under a 5 handicap if the weather cooperates!View attachment 9391842
This statement sums up so much for me.
I find my delivery has to change at the various sim places we frequent over the winter, and with some mats, I have to really pick the ball, and will get a majority of strikes low on the face. The thin miss is really good with the 250 & 150, and I’ve gotten away with a few that turned out much better than I deserved. The tungsten placed down low in the 150 is considerably smaller than the other models, but it works as intended.
That's great to hear. It's so cool when we see tech actually working for us in real life.
Those low strikes are working out so well for me. Had another yesterday that I expected to be well short. Had about 160 in hit 8 iron really thin. I normally take a good divot, but I don't think I even disturbed the grass on this one. Ball launched and hit the middle of the green, about 157 total. Similar to yours, it stopped within about 10-12 feet of the ball mark.
Can’t sing the praises of the U505 loudly enough. I’d be curious to see how that works for you - do you typically play a long iron/replacement in that slot, or do you lean toward a hybrid/FW?
Usually it's a set long iron in that spot. Hybrids have been hook machines for me, so I've always leaned towards long irons. Right now I have my 5 iron, which is my 200 yard club, give or take, and then I have a 7 wood that plays 220-225. So there's a little bit of a gap there, but I'd really like to have something reliable in that 210-215 range off the tee. I like my 7W, but I'm still not as consistent with it as I am with an iron.
Admittedly I have a smaller sample size than I’d like, because of our shorter season (and my limited outdoor experience with the 350), but I think you’ll like the sole interaction of the U505 coming from that model. It seemed to be very similar to me, despite the delivery being different between a long/mid iron. It’s got a decent amount of bounce, which helped me a lot in our conditions up here, and didn’t dig a ton in the softer stuff.
How does the launch compare to the 350s? I can get decent height on the 350 5 iron. I hit a lot of lower, more controlled shots with it off the tee and that would probably be the same for any 4 iron that I use. Would be nice to have some of that launch like the 350s when needed though.
