Mizuno shaft optimizer

I went to the PGA store and tried the Mizuno shaft flex optimizer and it recommended Project X 6.0 as the top choice as well as KBS and Dynamic Gold. All are in the 120-130 gram range. I had played these shafts for several years and had mixed results. Probably had my best scores with the PX, until last summer when I tried the Nippon 105X. I have consistently shot my best rounds with this shaft and was wondering why this would be. I almost wonder if I should buy a set of irons with the PX in them and test side by side on the course or just stick with what works. My only concern is that the weight is so different from what I am playing now it had me concerned.

The thing to remember with shaft optimizer is that it fits you into a profile and isn't for an exact/best fit. If you like 105X bring your club in and hit a similar or same club with PX 6.0 and compare results. Or look for a used club on ebay fit with PX 6.0 to try and see if you still like it.

Bottom line, if you have a shaft you like and your numbers (launch, spin, apex, etc) are good, why change? Again, it's only a recommender engine software.

Is the Nippon 105 offered by Mizuno. I watched a TXG video about the optimizer and I thought I remembered the Mizuno guy saying that wasn’t one of their options. Just a thought...

Easy to find out...

There is a misunderstanding of what the Mizuno shaft optimiser is (and is not)

It is a tool for quick short listing the significantly large number of custom shafts down to a manageable set for actual testing.

It is not perfect, it doesn’t always give the perfect shaft as the top recommendation (or perhaps even in the top five) .

The software selects shafts principally on weight, driven by the DNA Tempo factor. In the case of the OP the Modus 105 X has a bend profile that is fairly close to the Project X 6.0 it is simply lighter (8 grams) and a little softer.

The real strength of the optimiser is it gives the same starting recommendations regardless where or how often you use it (acknowledging software and custom shaft updates). This makes it a very useful tool in the big box store environment.

I used the new Shaft Optimizer at PGA Superstore and it recommended X100 AMT which I use, so that was reassuring. Nippon is not an option as a shaft upgrade through Mizuno so they won't show up as a recommendation.

The one thing I really liked was the lie angle recommendation. The lie board always told me I need to be 1* up but it never felt right and the ball constantly went left. The shaft optimizer said I should be 1* flat. Much better and consistent ball flight.

These responses were very helpful. Thank you.

I was in the same boat with my use of the optimizer it gave me C-taper and DG X100 and PX 6.5 as my top 3 but from prior use of them I knew I was looking for a lighter version shaft and went with comparing the C-taper lite X and Nippon 120 X and DG 120 x100 those choices were #5,6,7

ultimately went with Nippon 120 X and haven't looked back but was a great starting point for my fitting.

The one major flaw in the optimizer is that it has no way to consider or judge the subjective personal preferences of the individual. It's recommendations are based on rough generalizations of what types of shafts generally tend to work well with certain types of swings. It is NOT based on any objective concept of what is "right" or "wrong" for a particular swing type. So there will always be exceptions when dealing with those types of generalizations even though they are not far off a good percentage of the time. That's why the results always need to be verified through testing.

So if you already know from past experiences what works best for you, stick with that and don't worry about what the optimizer says.

There are a few Nippon options when custom ordering Mizuno irons: https://www.mizunousa.com/category/shafts+and+grips.do?gc=100939&content_component_qp=Shaft&content_type_qp=Iron&brand=Nippon&pp=12&sortby=ourPicksAscend&cx=1

Doesn't have their entire product line up, but the 105 & 120 Modus Tours are available, as is the NS Pro 950.

Could one of you Mizuno Shaft Optimizer experts let me know any shaft recommendations (steel or graphite) for these numbers?

77 3,4,4,8

Salesman let me try it but he didn't give me any shaft info.

Thanks in advance.

What's the point of letting you try it if he's only going to quote you the numbers it spits out. Any reason he couldn't give you the related shaft recommendations?

1. TT XP 95 S

2. KBS Tour 90 R soft step

3. Nippon NS Pro 950 R soft step

4. PX LZ Graphite R hard step

Thanks jgard.

Not sure why he didn't follow-up with me …. I'll claim ageism. I'm an old dude and he was a youngster …. either that or he became distracted with the cute gal that was asking for his help with a new driver ….

Shaft Optimizer puts you on the fish but catching the fish is different. Gives a fairly good place to start.

I used the optimizer and ended up picking a different shaft that was a much better fit for me. It is one snapshot in the process

Any chance anyone can share a login account/auth number for the PFS app? I have access to the optimizer itself...just need the auth code that goes along with the optimizer serial number. Thanks

Hi there,

Any chance I could get the Mizuno shaft recommendations based on these numbers : 88 6464

Thanks in advance.

This is what I got plugging your #'s in hope it helps you!

Thanks for the info.

Certainly backups my theory that my Modus3 120 Stiff iron shafts were a little too active.

Looking into shafts that keep the spin down a little and can handle my relatively aggressive tempo so this list will certainly help.

With Aggressive tempo recommendation is to go heavier shaft to help, thus all the shafts listed 125-130 grams. Quick tempo with aggressive loading, guys usually do well with PX 6.5 and C Taper stiff plus(125 grams) or extra stiff (130 grams). Those shafts do a great job keeping spin lower as well. A guy with smooth tempo will typically say those shafts feel like rebar lol. Timing of Release plays big role as well.

Have they ever come up with a Driver fitting shaft optimizer?

I went through the process of the Mizuno shaft optimizer myself and the recommended shafts were

P.X 6.5

C-Taper

P.X 6.5 LZ

my current gamers are DG X100 in Mizuno MP 67’s

The numbers I produce (95mph 7Iron at around 7400rpm), link me to these three shafts. With that being said, the Mizuno Shaft optimizer didn’t take into consideration WHY I was there. I told the club fitter that I don’t play as much as I used to (2 young children 3 yr old and a 6 month old) I am 43 years old, I had a back injury and now have lower back pain with arthritis........ I’m not getting any younger!

I was looking for something a little easier to manage (other than straight up blades with X-Stiff shafts) and something that was a bit more forgiving (I’m a pretty decent ball striker, but don’t play much) and also something that felt a littler softer, without throwing off my timing, or ruining my dispersion (let’s face it, if you are a decent ball striker, you can adjust to the nuances of each club after a range session) I tried a few clubs (settles on the MP20-HMB) and after the club fitter took into consideration, MY IMPUT, rather than just the Optimizers, he fit me into a Modus 120 X or TX shaft (I haven’t purchased the clubs yet, but I could go either way, they both had almost identical dispersion and feel to me, and I have to sell my clubs first or my wife will be looking at me sideways ?)

Anyhow, what are your goals to obtain? Is it Dispersion, Distance, feel, spin rates, flight or a happy medium of them all? I didn’t lose any dispersion with the Modus 120 from the PX 6.5’s and the spin rate wasn’t to much difference, nor was the overall distance (I had lower spin with the 6.5’s and they were marginally longer, the Modus flew a bit higher launch as well, but I don’t have flighting issues, so it was not in my purview) I tend to hit a slight draw, but hit the ball pretty straight overall. I found the PX were easier to fade for me with the longer irons while the Modus was easier to hit little punch draws ¯\_(ツ)_/¯ (I tested a 7 iron and a 4 iron of each)

in the end, a good fitter will be able to take into the whole of your golf game and provide insight as you walk the journey of iron fitting. I feel the shaft optimizer is a sterile mathematical enumeration based on static data.

If the numbers are razor thin in separation between shafts, go with feel would be my suggestion, after all you are the one hitting them, not Iron Byron ?

Surprisingly, they have just added driver shaft recommendations along with ball ‘fitting’ to the latest release of the software. Unfortunately I have lost my source for firsthand information. Based on a few trial runs it looks like the iron DNA, is simply extrapolated onto the driver shaft recommendations. This is flawed in many ways, so of little benefit.

The software does contain the EI profiles (traditionally these are only measured for the S flex then extrapolated for the others, so not 100%) so once again interesting since they have a wider range of exotic (expensive) offerings this year.
