While the star of Mizuno’s fall show will undoubtedly be their JPX925 Hot Metal irons, they don’t (on their own) provide the total fitting picture that the company is aiming for. Almost all of us have a “last effective iron” in our set. In other words, there’s a point where performance with irons degrades enough that it suggests an alternative, usually in the form of a hybrid or fairway wood. For some of us, that last effective irons comes quicker than others. Utilizing an immense trove of fitting and robot data analysis, Mizuno’s JPX925 Fli-Hi line is designed to fill out your iron set, giving you the same confidence in the lower reaches of your bag that you have in your 7 iron in hand.
Though they are hybrids at heart, the JPX925 Fli-Hi line is designed a bit differently. The trend in hybrid design has been to stretch out their distance potential, which certainly has its benefits, but it can present some gapping and playability issues. Fli-Hi’s are considered by Mizuno to be direct iron replacements, enabling golfers to maintain consistent feel, distance, playability, and height throughout the set.
Flow Profile Design and Material Selection

Flow Profile Design is an incremental change in club head shaping throughout the set. While having multiple hybrids that are shaped the same way is great for visual continuity, it does present some challenges when it comes to producing ideal launch conditions. For example, a 3 hybrid is often much more difficult to elevate than a 5 hybrid. By widening the club head’s profile in the lower lofts, Mizuno was able to drive the weight low and back, increasing launch where it’s needed. Conversely, the higher lofts are more compact.

Each Fli-Hi head is composed of two materials, each designed for a specific purpose. The 17-4 Stainless Steel face is built for durability, while the softer 431 Stainless Steel body provides speed and the opportunity for hosel adjustments.
Wave Sole and Speed Bevel

Wave Sole is all about providing consistency so you can hit more greens, even if you’re not the most consistent ball striker. It allows the face to flex easier and creates a wider area of high performance for you to strike the ball. It’s been designed to be especially helpful on low-face impacts, which are quite common as club length increases. Speed Bevel, which is visible in the grounded club above, is an interesting addition to Fli-Hi. Mizuno has shaped the leading edge (in their words they “blunted” it) to effectively increase the bounce, which makes the club more forgiving in the turf. They did this because they noticed their customers tended to swing Fli-Hi’s with more of a descending strike, similar to how they swing an iron.
Details
Keen eyes will notice very little offset in the Fli-Hi line. Again, Mizuno intends Fli-Hi to be a direct iron replacement, outfitting them with a .355 tip diameter so you can use your iron shaft. In addition to having similar assembly dimensions, the JPX925 Fli-Hi’s are the exact same price per stick as the JPX925 Hot Metal irons. New this year is the addition of two Fli-Hi options for left handers (19 and 22).

I’ve been sticking to range work and lessons so I haven’t played a round in a few months. I thought I’d hit my hybrid way more than I actually do so most of my observations are on the range anyway. Not that I think there’s something wonky with it, I just don’t have that distance enough. To answer the second question, I’m happy with the steel shafted hybrid. It just feels more like an iron replacement than a hybrid. Even though my dispersion from 200 is about average for a 10 cap, I feel like I’m focused on hitting a target rather than just “getting it somewhere up there”. It’s a very mental thing for me but I like the change in my thought process.
Pros:
More consistent feel and distance
Cost is the same as a JPX 925 Hot Metal family iron
My swing generates less hooks with these
Plays more like an iron than a wood
Slots in well with my set
Cons:
Distance seems shorter than previous graphite shafted hybrids I’ve played (may be a con for some)
Neither:
The steel shaft looks kind of like a throwback
Green holding is good but ball flight [I][B]looks [/B][/I]like it has a slightly lower trajectory than “regular” hybrids (no sim numbers, just looks)
I don’t see much negative with the JPX 925 Fli-Hi.
[/QUOTE]
Thanks for this. Can you share some detail about the distance as compared to your HMP? Curious as to the gapping, ie your 4i carries ??? and your 5 hybrid carries ???. Thanks.(I think I’m going to replace my 5HMP with the 5 hybrid). thanks.

[/QUOTE]
I don’t have a 4i since 5i has been the longest club I can consistently hit for awhile. These are my distances from 5W to my shortest iron.
5W – 214
4h – 199
5i – 187
6i – 177
7i – 165
8i – 153
9i – 138
PW – 123
GW – 110
The 6i to 5i gap drops to 10 yards which reinforces my cutoff. The 12 yard gap between 5i and 4h is close to my iron gaps of 12-15 yards. I don’t mind the 15 yard gap to 5W. I like 15-20 yard gaps for my woods since they’re more of a shotgun approach rather than an accuracy approach.

Now that some time has passed, anyone with these have some pros/cons coming from “regular” hybrids?
I know the steel shaft debate in these sparked a little interest, so curious what anyone has to say about the change to “matching” these shafts to your normal iron shafts versus a traditional hybrid set up
[/QUOTE]
Yea, this is a good question.
The more time that goes by, the more I think this is the “normal”hybrid. It’s so easy to hit and fits into an iron setup so well.
I’m trying to figure out my exact hybrid configuration for 2025 and this one is a top contender in the 5h slot. If I go with it I’m going to install a DART 90 into it. Right now it still has the steel shaft and I want some consistency with my irons.
I got a chance to hit this club once over the past 2 rounds. Like I said, it’s not a common distance. I hit a pull draw because I tried to give it a little extra due to weather. It felt like a pull hook swing in previous hybrids. I left myself pin high left with about 20 yards to the pin.
One shot isn’t a big sample size but it reinforced what I’ve been seeing since putting it in play. It can draw but it doesn’t want to go hard left. If there’s one thought that stands out about the FliHi, it’s that it’s a playable club I don’t really need to protect against.
Man. I have a Dart 90 that would probably work in this. Hmmmmmmm.
Just took delivery of the 22* to replace my 5 iron. Hope it works out!

Agreed, but how do they compare with the ST Max size-wise? Giving these a hard ponder but I can’t find them locally, so I have to go with anecdotal accounts…side by side photos would be especially helpful. ?
Sorry, I don’t have the ST Max to compare. Any other hybrids you have in mind that I could ballpark?
It’s not a big hybrid imo. Standard game improvement style head.

It’ll probably appear larger than those TSR’s and possibly a bit more closed off. Won’t be extreme with either thing, but a bit for sure.

Sounds good. This might fit right in well with a Recoil Dart shaft easing the transition to my Recoil-shafted irons.

That was exactly what I was going to do at one point, but then product reviews sort of pushed it to the backburner.

Good information…now you’ve got me pondering hard.
I’m getting more and more comfortable with my JPX925 Fli-Hi 19* and 22* hybrids. Shots are now going straight and distance is improving. I’m now hitting them with more of an iron set-up and swing, and less like the 5w and 7w they replaced. This has definitely improved my dispersion. While the distances are just a bit less than with the 5w/7w, I can hit the hybrids more often from different lies. Confidence in these clubs is a lot higher now, and I’m really enjoying the versatility.
So what type of player should go for Fli-Hi 28 vs ST-Max 28? Want to change my 27* iron since my swing speed has dropped significantly.
[USER=1193]@Hawk[/USER] thanks for the writeup!
Do you think Mizuno gets enough credit for the Fli-Hi?
By this I mean they have been doing these for years and when I last recall they offered them as a free upgrade for sets? As in you order 5-PW and want the 5,6 irons to be Fli-Hi models instead it can be done.
Compare these to .. the CLK version …
What would be the difference ? Please

They absolutely do not get enough credit. It’s a severely underrated club for someone who couldn’t hit hybrids well because they always hooked. I could hit my previous hybrids far enough but the accuracy wasn’t what I wanted. They kept going left.
The JPX 925 FliHi is the same price as the JPX 925 Hot Metal line. So the option to create a set at no upcharge using hybrids is still there. It’s a really nice feature and helped to round out my set nicely.
I rarely, if ever do this, but here we go:
I’m pretty much a sarcastic, skeptical person, which comes from growing up in Vermont where there is nothing to do but drink and be miserable for 7 months out of the year. Couple with my professional career, which is very data driven..”In God we trust, all else bring data”, I don’t fall into much if any of the mfg hype. I mean, of course their marketing says it’s great, duh.
Played today, had a par 3 that was 188 into….hit a toey, not so good 22* Fli-hi, which ended drew back into the green about 30 feet short. By itself, not a great shot, but understand how really bad the strike was, and you’d be impressed.
Overall, everyone should really try/have one of these for a longer iron reaplacement. It really is that good. Really.

Biggest difference on paper is going to be the adjustable hosel on the ST Max. Pretty big range of adjustment there.
Other than that, I think it will come down to fitting preferences. For the money, it’s hard to beat the Fli-Hi as a direct iron replacement.

I think a big part of it is not getting credit like you say, but they are also marketed a bit differently. Some of it’s on Mizuno. They tend to release them and market them in conjunction with their iron sets and that’s going to put them into a box in consumers’ minds imo. Also, it seems like every “iron replacement” hybrid doesn’t get the same love some of the distance oriented hybrids do.

The price difference right now is $10 so money isn’t a big consideration. Is there a significant difference in playability and forgiveness? Is the ST-Max head much larger in size?

I’ll piggy back on this question…I’ve only seen the lower lofted JPX hybrids, and those are too big for my needs. I know the heads scale down as the lofts go up, so my question is how much smaller do they get? I’m looking for something closer to the GT3 profile.

Hope this helps:
If you’re comparing the ST-MAX hybrid to the JPX Fli-Hi, they are really designed to be two different animals.
ST-Max is more of a true hybrid.
Larger head side. Deeper CG. 0.370 tip to receive a hybrid shaft.
JPX Fli-Hi is more of what we call a “Direct Long Iron Replacement”
Blends to a set of irons better (ie smaller)
0.355 tip to receive the same shaft you put in your irons.
It’s for that person who is seeing diminishing distance returns from the “next longest” iron. So this would go in its place to help to maintain distance.
