Mizuno Performance Fitting System
By Rob Miller
GolfWRX Staff
In golf, the name Mizuno is synonymous with great irons. Chances are we all know a player – and probably a good one – that gamed ‘Mizzys’ growing up and hasn’t switched iron brands since. Great feel combined with classic good looks is hard to beat. Over the years, Mizuno expanded their lineup to include models for golfers of all skill levels while still staying true to its roots of function, clean looks and mostly ‘grain flow’ forgings. Through the years, Mizuno irons have been consistent Gold and Silver winners on Golf Digest’s annual Hot List.
Of course, when you have many different iron models to chose from, you need to properly fit golfer to club and shaft — not necessarily an easy task. Mizuno created their Performance Fitting System to help us out. GolfWRX is working with Mizuno to fit some of our equipment reviewers into the proper iron/shaft combo. I recently was invited to see what it was all about.
I have been through a few fittings before, but never the Mizuno Performance Fitting System. The claim is “In just a few swings, Mizuno’s Shaft Optimizer ends the guesswork by measuring five critical aspects of your swing to determine your unique Swing DNA. “ Having tried it out, I have to say it works great.
Your information is entered into Mizuno’s patented Shaft Optimizer software, which then recommends a shaft with performance characteristics perfectly matched to your individual swing.
I took about a dozen swings, but honestly as little as three is all it really took. My numbers came up and created my own swing signature which measured:
- Club Head Speed: How fast the club head and shaft are moving during your swing.
- Tempo: How quickly you transition from your backswing to your downswing.
- Shaft Toe Down: Measures how far the shaft bends in a downward direction during your downswing.
- Shaft Kick Angle: Measures how far the shaft bends forward during your downswing.
- Release Factor: How and when the club head and shaft are released during the downswing
The kicker is the Shaft Optimizer is it does not care about the quality of your strike of the ball. Good contact or bad, you have a swing signature and its job is to find it.
Once the data was input by my fitter, the system gave me a few shaft suggestions, including Dynalite Gold XP and Project X 5.0.
With the Shaft Optimizer portion done, it was time to decide on clubhead / shaft combo by hitting balls at the range. I alternated between MP-59 and JPX-800 Pro heads with Project X and Dynalite. Ultimately, deciding on JPX-800 Pros with Dynalite XP S300. This choice is up to you. Next half-dozen hits off a lie board confirmed 2 degrees upright.
The length of the process varies depending on how many balls you want to hit. Being a range rat, I took my time, but you could be done easily in under an hour.
So here’s the best part. Your Mizuno fitter inputs your order directly into the system. Would you rather bag an MP-R12 50* rather than your set’s Gap Wedge? You can swap out wedges on the order screen. Rather play a Fli-Hi than your 4 iron? Done. Want a mixed set of 800 Pros and MP-59s? Mizuno can do that too (I was tempted). It’s all customizable.
Finally, Mizuno has perhaps the best turnaround in the industry. Orders are submitted by the rep on the spot and you’ll be bagging your new Mizunos within 7-10 days. In my case, it was seven on the nose. Mizuno touts this as ‘the best turnaround in the industry’.
So, how are the irons, you ask? (After all, the proof is in the pudding). Happy to say I entered new territory with my Mizunos. I shot my best score ever, 2-over par for an 18 hole round, just the third time I put them in play.
In the market for new irons? With iron models made for every type of golfer, you can perhaps find your perfect set of Mizunos– and go from custom fitting to the course in about seven days.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

Name every set of irons you’ve owned – GolfWRXers discuss
In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.
@Lamosteve began:

Our members in the forum have been offering up their own collections. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

I had the same results and have played both the dg s300 and dnlite s300s. I do get a tiny bit more airtime with the lights but ive always used the dg s300s so thats probably why i fit them honestly.
this is real fitting here, just like the pros.

This whole concept is based on the old True Temper Shaft Lab loading device. It is the real deal. It can work with woods to with a proper fitter.

I actually just went to a fitting today. I must say I was impressed by the shaft optimizer. HOWEVER, i feel as a higher handicap that its not something i would take true to heart. To be honest this wasn’t my first fitting with Mizuno. I am a Mizuno nut btw. Anyhow fitting 1 told me to go with standard dynamic gold shafts stiff. Second fitting told me to go with dynamic XP extra stiff. ???? i was confused. I honestly feel that for someone who may not have their swing down consistently it may be a waste of time to get fitted clubs and when you change your swing you have to change to another. Comments thoughts?

Hmm.. In fact, DG stiff and Dynalite (not “dynamic” btw) XP extra stiff are pretty similar in flight and spin except DG stiff might be slightly heavier.
