Mitsubishi Diamana WB Shaft Review

50 Words or Less

The Mitsubishi Diamana WB shaft has the classic Diamana smooth feel but with more power than you might expect.  Low launch, low spin.  Very consistent directionally.


In the shaft world, new names pop up and disappear every year.  Mitsubishi’s Diamana line has been the exception.  For twenty years, it’s been the pinnacle of performance, winning Tour events and fittings all across the globe.  To celebrate this major anniversary, Mitsubishi is offering the new Diamana WB – named to honor the White Board, one of the shafts that started it all.


It’s only fitting that the Mitsubishi Diamana WB goes big to honor the Diamana aesthetic.  The classic Diamana flower band performs figure-eights around the shaft, surrounded by larger, white flowers above and below.  This shaft sees a slightly modified Diamana branding, though the look will still be familiar to longtime fans.

The major aesthetic change for the Diamana WB is the switch to a matte finish.  With Diamana PD [review HERE], there was a very glossy look.  The WB is much more subdued with only the very slightest hint of iridescence on the Diamana logo.


Over the last couple years, Mitsubishi has offered a lot of shafts in the Low Launch, Low Spin family.  From the aforementioned PD to the Kai’li White [review HERE] to my gamer, the TENSEI 1K White, there were slight tweaks aimed to fit every player.  This left me curious where they would take things with Diamana WB.

When I first took the WB to the range, I found a more explosive feeling than I expected.  My speed has been good of late, but not all time high.  In spite of that, I felt the 63-X driving through the ball with purpose.  The Mitsubishi Diamana WB has the trademark Diamana smoothness and a very solid feeling at impact, but it was the explosion in the mid section that really left an impression on me.

Interestingly, Mitsusbishi rates the Diamana WB as being stiffer in the butt and mid than the Diamana PD.  The tip section is one notch softer (Medium+ to the PD’s Firm), but I felt that the tip was very stout.  As usual, this speaks to how personal feel is and that you can’t fit a shaft on paper.


The phrase that I kept putting into my testing notes is not one I typically associate with low/low shafts: “Fun to hit.”  That’s particularly noteworthy considering it’s winter in Chicago, and my swing reflects that.

For my first few swings with the Mitsubishi Diamana WB, I was trying to focus on the feel.  But that feel led my wandering eyes to my launch monitor which was showing a couple MPH boost over my Tensei 1K White [review HERE].  More speed – with a fast feel – is definitely a big part of the fun.

As I hit more shots, what I appreciated was how consistent the launch angle and direction were.  Typically a shaft with this much feel would invite more shots left.  The Diamana WB kept everything just as straight as my TENSEI 1K White.  In terms of trajectory, the WB was actually a touch lower, and the spin remained in my normal, low range.

For the shaft nerds, the Mitsubishi Diamana WB shows the company using a variety of their best materials.  In the handle, there’s 80-ton DIALED pitch fiber for more stability and energy transfer.  MR70 runs the full length of the shaft for strength and feel.  Finally, high modulus 46-ton fiber is applied in angle plies to lower the torque and add to that smooth feel.

The Mitsubishi Diamana WB is offered in five weight profiles: 43, 53, 63, 73, and 83.  Mitsubishi is showing a big commitment to light weight by offering the 43 gram version in five flexes: R2, R, SR, S, and X.  Both the 53 and 63 are offered in five flexes, too, just shifted up one: R, SR, S, X, and TX.  The heaviest versions come in just three flexes: S, X, and TX.


The Mitsubishi Diamana WB is a shaft worthy of the White Board name.  It has the low launching, low spinning performance that higher speed players love but with a feel that’s miles from stiff or boardy.  Visit your Mitsubishi fitter to check out the latest generation of Diamana.

    What is more “fun” to hit in your opinion? The WB or 1K?

    • Matt Saternus


      The WB has a more explosive feel, to me, so I would say that.



    • Hi Scott great review

      Im gaming tensei 1k white too

      How do you compare the ball flight and total distance between these 2 driver?

      Is the diamana more forgiving?

  2. James Ellenberg

    Any comparisons you can give vs Kaili White?

  3. Thanks for a great review Matt. I asked you to compare your 1K to my first generation AV White RAW 60gX a while back and you replied that there’s not a lot of difference. Any notes on the new WB in comparison? Thanks

    • Matt Saternus


      I think the feel described in the review is quite different, relative to the difference in performance.


  4. How would you compare this to the ventus black?

  5. Great review, thanks for posting it. I know you often say you can’t compare different shafts reviews from different days, which I agree with, but your numbers with the Ventus TR blue are nearly identical. Do you have any feedback on the difference you felt between these two shafts? I know that there’s way more than just numbers for a shaft. Curious if you they felt similar or different in your opinion of course. Thanks and keep up the great posts!

      That’s an interesting comparison. I have no data on this, but my sense is that the WB would spin and launch lower, head to head. The feel is similar, insofar as they have about the same amount of kick/help/action, but it’s not in the same place.



  6. Incredible points. Outstanding arguments. Keep up the good work.

    Would love to see a review on the Blueboard in this 20th redu. I just bought the Blueboard and it feels cheap compared to my original Blueboard I use now. I can rip the old girl but the new one just hooks out unless I hit it like a senior shaft. I’m very disappointed except it looks good. I have the 63stiff version.
