Mizuno Performance Fitting System

Published

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.

Look for Mizuno Iron reviews from GolfWRX very soon.

    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.

What GolfWRXers are saying about the best “5-woods under $125”

Published

on

@golfexchangeapp

In our forums, our members have been discussing 5-woods, with WRXer ‘gary3aces’ looking for a 5-wood for between $100 and $125. He’s looking to replace his current “M2 5 wood with something a little easier to hit”, and our members have been discussing the best options in our forum.

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.

  • C6 Snowboarder: “Take a look at a used Callaway Heavenwood in the Epic Flash model = pretty Friggen sweet. It is Heaven!”
  • Golf64: “Bang for the buck, hard to beat Cobra, but find Ping one of the easiest to hit off the deck. Since you are limited in the funds dept., maybe an older model Ping 5W would do the trick?!”
  • tilasan1: “G400 7 wood turned down or just use it as is.”
  • jbandalo: “Fusion fairways. Highly underrated, cheap, easy to hit and go for miles.”
  • RyanBarathWRX: “PING G fairway would be hard to beat and easily in price range:
  • Nelson.br.1515: “Another vote for the Callaway Big Bertha Fusion. Great stick!”

What GolfWRXers are saying about “blending Ping i500 irons with Blueprints”

Published

on

In our forums, WRXer ‘ballywho27’ has asked for thoughts on combining his current Ping i500 irons with the brand’s Blueprint irons. ‘Ballywho27’ is considering going “i500 in 3-4 iron and blueprint 5-W” and has asked for fellow member’s thoughts on the idea – who have been sharing their takes in our forum.

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.

  • jblough99: “I had a combo set for a minute, 3-5 I500 and 6-PW Blueprint. I could not get used to the transition, HUGE difference in looks at address. If I had it to do over I would just go 4-PW Blueprint and maybe a 3 I500 with graphite shaft as a driving, iron.”
  • animalgolfs: “iBlade{5i} – BP{6i-pw}. That’s my combo.”
  • Chunky: “I have i500 4-5 and Blueprints 6-PW. As mentioned above, there is a significantly different look at address. More importantly for me, the i500s are 1/2 to 1 club longer than the BPs (they fly much higher, too). Make sure you account for that added i500 distance when blending lofts or you’ll have a large gap.”
  • howeber: “I’ve done that exact set — 3 and 4 i500 and 5-PW Blueprint. It’s perfect for me since the 3 and 4 are more like a traditional 2 and 3.5. 4 is usually the longest iron I carry, so I like a little extra oomph out of it. At the end of the day though, when I finally tested them vs my MP4s, the Blueprints performed identically, while the i500 launched a little higher (same specs same shafts). Mizzys are still in the bag.”

GolfWRX Vault: Avoid these 5 club building disasters

Published

on

It’s never too late to go back to basics, especially when it comes to club building.

Even with modern new club release cycles the do’s and don’ts of building clubs haven’t changed much in the last few decades except for clubs with adapter sleeves and greater amounts of multi-materials incorporated into the design.

With that in mind its time to revisit an article from the GolfWRX Vault from June 2016.

——————

I’ve been fitting and building golf clubs for more than 15 years, and in that time I’ve seen a lot of really poor workmanship—stuff that would make most GolfWRXers cringe. But like anyone who ever did anything new, I didn’t start being naturally good at putting together clubs. It took a lot of time, ruined components, and trial and error to get where I am today.

I believe my attention to detail now stems from the fact that my dad was a machinist by trade, and anytime we ever worked on something together his attitude was to take your time and do it right the first time. My dad’s approach always had an impact on me, because I feel that if you do something right — even when it takes a bit longer — the job is not only more satisfying but also makes things work better and last longer.

The goal with this article is to help WRXers avoid the most common mistakes and assumptions in club building that lead to broken or ruined clubs, as well as real danger.

Over-prepping a graphite shaft

The shaft on the left has been prepped properly. The one of the right, which has noticeable taper, shows signs that layers of graphite have been removed.

This happens far more than it should, and can ruin an expensive new shaft purchase. To prepare a shaft properly for installation, you only need to remove enough of the paint to make sure that the epoxy adheres to the graphite. This is also true for the inside of the hosel.

Be careful to remove residual epoxy, dirt or rust (common with forged carbon steel club heads that have been sitting around for a while), or some type or solvent like the one used to put on grips, as it can cause of bond to break down very quickly. A proper reaming tool, a wire brush and some compressed air (either a small can or a large air compressor) can make cleaning simple, and prevent a golf club from falling apart.

UPDATE: Over prepping specifically applies to shafts that are designed to go into parallel heads and is especially important for 335 shafts with less material at the tip going into drivers and fairway woods. For information on how to properly taper a shaft to go into a tapered head, check out the video below:

Overheating a Shaft When Pulling it

This is what happens to a graphite shaft when overheated.

This is what happens to a graphite shaft when overheated, and the resin holding the graphite sheets together breaks down. It’s not always as noticeable, but if the shaft starts to fray it means the bonds have been compromised and it’s more likely to fail. 

Overheating a shaft when pulling it is another common mistake that can result in ruining a golf shaft. It also highly increases the chance of breakage. There are quite a few methods I’ve learned over the years to remove a shaft from a club head, from heat guns to large propane torches, but personally I find that using a small butane torch with a regulator for graphite offers the best results. It allows a club builder to easily control and focus the heat only where it’s needed. Bigger torches are fine for iron heads, as long as you don’t damage any plastic badges in the cavity or materials in slots around the head.

One of the best advances in club technology has been the invention and mass adoption of adjustable hosels. They not only help golfers adjust the loft, lie and face angle of club heads, but have also greatly decreased the need to pull shafts. So as long as a golfer is staying with the same metal wood manufacturer, they can usually test several different clubs heads with the same shaft, or vice versa — several different shafts with the same clubhead.

That being said, one of the most important tools that any hobbyist club builder should have or have access to is a high-quality shaft puller. It’s a necessary tool for anyone who wants to do repairs and helps prevent damage to a shaft while pulling it. The more linear pressure that can be applied to the clubhead, and the less heat used to break down the epoxy, the better. It makes sure both the shaft and the head are reusable in the future. For steel shafts, you can use a bit more heat, and twisting isn’t a problem. Again, with increased heat, be careful not to damage any of the badging, or permanently discolor an iron head.

Botching a Grip Installation

Using calipers and two-sided tape, you can replicate the taper of shafts to makes every grip feel exactly the same size in your set.

Using calipers and two-sided tape, you can replicate the taper of shafts to makes every grip feel exactly the same size in your set.

This one seems simple, but when really getting down to professional level detail, it is quite important. We ALL have a preference and different opinion of what feels good in a golf grip, as well as different sensitivities. For example, we all have the ability to figure out what apple is bigger, even if blindfolded because over time we all develop brain function to understand shapes and sizes. This also applies to grips. If you use the same grips on your 13 clubs, you could potentially have 4-5 different final sizes depending on how many different types of shafts you use, because many shafts have different butt diameters.

Some shafts have larger butt diameters, while others taper faster than others. That’s why it’s very important to own a quality set of vernier calipers, and know how to properly use them. It’s also the same for putters, since many putter shafts are smaller in diameter. I have lost count of how many times I’ve had people bring me, putters, where the bottom half of the grip is twisting and turning because the installer never paid attention to the interior diameter of the grip, the exterior diameter of the shaft, and how it changed from top to bottom.

Using epoxy that’s doomed to fail

An example of epoxy that although not completely set, is no longer safe for assembling clubs.

An example of epoxy that although not completely set, is no longer safe for assembling clubs.

I’m a bit of a physics nerd and garage engineer, so this is one of those topics that goes beyond just the physical aspects of club building and into the realm of chemistry.

Here comes my nerd-out moment: In the simplest of explanations for a 0.335-inch driver hosel with an insertion depth of 1.25 inches, the amount of calculated surface area the epoxy can bond between the shaft and the head using the internal dimensions of the head is 1.49 square inches. That’s not a whole lot of area when you consider the centrifugal force being applied to a driver head traveling at 100 mph, and then the forces of torque that also come into play when a shot is struck.

In a PERFECT world, almost zero torque is applied to a shaft when a shot is hit on the center of gravity (CG) of the club head, perfectly aligned with the center mass of the ball, while traveling in the intended direction. This is vectors 101 of physics. Unfortunately, almost every single shot is NOT hit like that, and this is where the epoxy bond is put under the most amount of stress. Lap shear strength of epoxy goes beyond me, but it proves that building a golf club is not just cut and glue after all.

Note: For those of you curious, the most popular epoxies are rated for 4500 psi. 

As far are actually working with epoxy, first things first. Always check to see if the epoxy has a best-before date (yep, just like milk). Also, never store epoxy in direct sunlight. If you are using epoxy from a tube in a dispensing gun, you are using what is an almost foolproof method. Plunge out the necessary amount, mix for about a minute (mix! don’t whip), and remember, the less air that gets into the epoxy the better. If air gets in and the epoxy cures with bubbles in it, then you end up with a club that will often “creak.”

For those using two parts in larger bottles, the best way to ensure proper ratios is to pay attention to the weight ratio rather than volume. This isn’t arts and crafts; it’s chemistry, so by using the weight to calculate the ratio you will get the right amount of each part every time, and help decrease the risk of failure down the road. If you have mixed a larger batch and plan on building quite a few clubs at a time, you really have to pay attention to the consistency and viscosity as time goes on. You don’t want to glue a club head with epoxy that has started to set.

Turning an Extension into a Shank

The difference between a good shaft extension (bottom) and a bad one.

The difference between a good shaft extension (bottom) and a bad one.

This is one of those subjects I don’t even like to talk about. I very much dislike using extensions when building clubs, especially clubs with graphite shafts. Going back to my “do-it-right-the-first-time” mentality, extensions are a Band-Aid fix to a problem that requires surgery. They also counter-balance the club, and by their very nature create a weak point because of the small wall thickness at the butt end of a shaft. The only clubs I don’t mind extending on a regular basis are putters since they are never put under the same level of stress as a club being swung at full speed. I also never extend a club more than 1 inch, because I have been witness to horror stories of clubs that have been overextended that not only break but rip through the grip and cut people’s hands very badly.

If you are going to extend a club, it’s important to make sure the fit is very snug and doesn’t cause the extension to lean in any direction. It’s also best to have the epoxied extension cure with the club on its side to avoid an excess epoxy from running down the shaft and breaking off and causing a rattle.
