Mitsubishi Diamana GT Shaft Review

50 Words or Less

The Mitsubishi Diamana GT shaft gives players ample control of their ball flight while still providing smooth feel and a subtle kick.  Feel and performance fall between the Diamana PD and TB.


In 2020, Mitsubishi expanded their most heralded shaft line – Diamana – to include the ZF [review HERE].  This blend of their Blue and White profiles was an immediate success and has won multiple major championships.  For 2022, the ZF has been given the 5th generation upgrade and is now known as the Diamana GT.  I took a look under the hood to see what’s new.


At a glance, the Mitsubishi Diamana GT looks very similar to the Diamana PD [review HERE].  Putting them side by side, however, makes the differences obvious.  Just below the grip, the PD is white where the GT is silver.  Also, in the logo-down position, you can see that the lower section of the GT is darker than the PD.  The most obvious difference is in the Diamana branding – the PD is black where the GT has a beautiful iridescent outline.

The branding and graphics on the Diamana GT are consistent with the other fifth generation Diamana shafts.  All of them share a large Diamana logo across the center.  The signature flower band is located just below the grip with a ringed “D” graphic below that.

Overall, the silver and black color scheme keeps the Diamana GT flying below the radar, but the moment you get into the sun the iridescent graphics explode.


My first swing with the Mitsubishi Diamana GT sent me to my phone to write a single word into my notes: “Butter!”  This shaft feels incredibly smooth in the butt and upper-mid section.  It sits right on the border of smooth and active.  I’m hesitant to say that it has a real kick – it’s not quite a hinge-and-explode sensation – but it’s very close.  In contrast, the tip section is very stout and predictable.

This feel puts the Diamana GT somewhere between the PD and TB [review HERE].  I tested it head to head with the PD, and the GT is clearly more active/smoother in the butt section.  However, it doesn’t take that activity all the way to the tip like the TB does.  If you like both those shafts but want something in the middle, the GT may be perfect for you.


Per Mitsusbishi, the Diamana GT has launch and spin characteristics that fall between the PD and TB.  Where the TB is mid-high launch with mid spin and the PD is low launch, low spin, the Diamana GT is mid/low in both launch and spin.  To crib from their notes, it “launches lower than TB and spins more than PD.”  This fits precisely with what I saw in my testing.  The Diamana GT launched higher and spun a bit more than the PD.  I really like that the differences were not huge – this combination of offerings allows for a fine-tuned fitting.

*Taking a brief pause here to remind you that the launch monitor data from one review should never be compared apples-to-apples to another.

In terms of accuracy and shot shape, there was minimal difference between the PD and GT for me.  Both shafts feature strong tip sections which is something I always gravitate towards.  Any time that I made a good swing, the ball flight was very predictable.  The stout tip also did an excellent job keeping toe and heel shots from curving into trouble.

I found myself enjoying the GT more as I got deeper into the testing.  Where the PD invites me to swing all out, the GT has just enough action to get me to throttle back 5-10%.  It’s the difference between putting the accelerator all the way to the floor and leaving a little breathing room.  I haven’t had much course time with the GT yet, but I expect that extra “oomph” from the shaft can come in handy on the last few holes.

Going back to fitting, one of the upgrades that Mitsubishi has implement across all the fifth generation Diamana shafts is Consistent Feel Design.  What this means is that there’s less variance in the shafts as you move between weights and flexes.  Specifically, butt diameter and balance point are held much more constant so you can isolate the variables of weight and flex during your fitting.

The Mitsubishi Diamama GT is being offered in five weight classes, from 40 grams to 80 grams.  The heaviest models, 70 and 80 grams, are available in stiff, X, and TX flexes.  At 50 and 60 grams, golfers can choose from regular, S/R, stiff, X, and TX.  Finally, the lightest Diamana GT adds an R2 flex but drops the TX.


The Mitsubishi Diamana GT is going to be that perfect Goldilocks shaft for a lot of golfers.  It takes the strong tip section of the White profile with the Blue’s smooth kick to make a truly special offering.  Visit your Mitsubishi fitter to give it a try for yourself.

  1. If there was ever a shaft that I would buy without testing…this would be it. That iridescence is nice.

  2. Matt, your review of the ZF mention a tendency to turn the ball over. I fought a bit of a hook with the ZF myself, did you find a left to right flight at all with the GT? Thanks!

    • Sorry, I meant did you find a draw bias with the GT (I’m a lefty so I wrote L to R by. Intake).

      • Matt Saternus


        No, the ball flight (in terms of direction) was more of what I’d expect from the White profile due to the stiffer tip section.



        • Hi Matt, I’ve been awaiting the GT to be released however I’m actually drawn between the GT and Kai’li white. I’ve read both of your reviews on them and wondered how similar/different you find them in term’s of stiffness, smoothness and active kick. Thanks Simon

  3. Matt, how does this compare to the Fujikura Ventus Blue TR? Sounds like a very similar concept. Thanks.

  4. Thanks for pointing out the Ventus Blue TR review, Matt. How would you compare the two shafts to each other, as their profiles and attributes sound very similar? Thanks.

    • Matt Saternus


      You’re correct, the two shafts are similar. If I had to highlight one difference, the Ventus kicks a little further toward the tip than the GT.

    Curious how your numbers compare to your gamer, specifically are these target numbers for you? I only ask because we share similar club speed, I’m a little quicker averaging 108-110. Ball speed is nearly identical, 160 is my ceiling but 157-158 is most common. I however target 12* launch and 2400-2600 spin on my driver. Your numbers are obviously a product of dynamic loft but your review fails to note the driver and loft settings nor your strike pattern. My gamer is TS3 @9.5 w/Diamana D60+ TX. My misses tend to be toward toe. Your much higher launch and lower spin could be due to higher loft setting but strikes low on face or maybe lower loft but strikes high on face.

    I’m currently getting fitted for the TSR and Paradigm drivers, my fitter is pushing the Ventus Blue TR, but I’ve always preferred the smoother flexing Diamana, Speeder line if Fujikura. My fitter unfortunately cannot get his hands on the GT50 or 60, only 70 & 80 at this time. He has the PD and TB in demo matrix in all weights. Feel like this might be the perfect shaft but if it produced the launch and spin you are showing, that would not be ideal for my preferred numbers. Any suggestions?

    Great reviews.
    I have a simple question. Do you game 1K in S flex or x?
