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).

Oops, I did it again….
These hybrids are being slept on. They are just consistent workhorse iron replacement clubs. Does it have a fancy adapter or weight to move around? Nope. Does it need it because you can bend the loft and lie? Nope.
It’s just a great club that fits the exact purpose I’m looking for. A direct iron replacement for the 5 and 6 irons.

They really are workhorses. Mine stays covered and barely comes out to play but it’s there whenever I need it. Somehow the familiarity never goes away.

I wonder how well they would blend into some M13 or S3? 🤔

I believe Mizuno intentionally tries to blend their hybrids and irons. I have the 243s and a FliHI 4H, the 5i and 4h blend almost perfectly. I have a 12-14 yards difference between the two. I’ll wager they blend fine with the M13s.

Pretty well I would think. I need to come out your way so you can give them a cut.

I actually had a bit of a brain fart recently. Was loving my T150 six iron so much, I thought maybe I could slip my MP-18 Fl-Hi five iron back in the bag in place of my 28* JPX 925 Fli-Hi…a couple of swings on the range later, and the MP-18 slipped quietly away.
[/QUOTE]
Golf is a complete mindf*ck…I was on the sim again today, and the JPX 925 Fli-Hi seriously underperformed relative to the T150’s, so much so that I started to think I might need to replace it with a T150 five iron in that slot. This, despite the fact that the Fli-Hi continues to do the job so well outside. 🤯
These hybrids are being slept on for those looking for direct iron replacements. They just work so well and to put your same iron shaft into them is just such a good call. The swing feels are the same, just a higher performing club head for those middle to long iron spots

Stop it, I’ve been strong pondering one of these in my 5H spot (as a 5i replacement) for quite a while now.

Should these be played as a 6h in 6i spot? I currently have a 6h in the 5i spot and it gaps well.

You know, I need to check as they don’t have the number anywhere on them, just the loft. I have the 28 deg and 25 deg and they seem to work really well as my 5 and 6 iron.

I will do no such thing. I’ve been pretty impressed with them and that should be shared. Happy to answer any specific questions you may have.

Thanks! We’ve hears lately from some other OEM’s that they consider the hybrids to be number for number replacements. But I’ve always numbered up, so to speak.

Merely as a frame of reference, as we know loft isn’t everything, there is a 2° difference between what I call my six hybrid and my seven iron. It is gapping really well for me.

Has this happened yet? Can’t argue the price. Can’t argue the shaft with their library to make it match your irons. Can’t argue the performance.
First hole in league last night was a long par three. I absolutely caught the six hybrid thin yet all the group was complementing me on my tee shot. What they did at the bottom of the face to maintain performance there is really well done.
I could not get over the super draw biased 5h and was replaced by Honma. Some reason 4h works so well and is in my bag.

Curious the 4h is solid but 5H over draws for you. Any thoughts why?

It hasn’t happened yet. Once it cools down enough to spend some time at the range with the LM1, I need to see if I even need a club in that slot between my 6i and 9W.
I currently have a 5H in the bag but rarely ever use it – I started hooking it and now I’m reluctant to even pull it.
If the Fli-Hi fits for gapping I’ll probably pick one up.

I think it is due to heavier swing weight and head design.
My previous 5h was Honma TW747. The new one is TW 767.
I have a pair of these as direct iron replacements for my 5 and 6 iron. Yesterday, flared a drive right so had to get over a big tree from 185. Knowing I didn’t want to hit the tree, I pulled the 6h which is about 175 for me. Ball got up so fast and landed on the front edge, about where I would expect, clearing the tree with ease.
This isn’t a story about a GIR, but about how good these are as iron replacements. The ball gets up quickly and goes the set distance. I haven’t seen any rockets that other hybrids can sometimes seem to give. Clearly I put a good swing on the ball, but I’m convinced I don’t clear that tree with a six iron, even with a good swing on the ball.
