Mitsubishi TENSEI Pro White 1K Shaft Review

50 Words or Less

The Mitsubishi TENSEI Pro White 1K uses premium 1K fiber to create a more consistent, stable shaft.  More active butt section with a more stable tip.  Noticeably different than the standard TENSEI White.


Equipment-obsessed golfers know that 2021 has been a year of material stories in the shaft world.  The major players are turning to aerospace and military-grade fibers to make their shafts more consistent and higher performing.

After releasing their AV RAW line of TENSEI shafts [reviews HERE], Mitsubishi one-upped themselves by bringing out the TENSEI Pro White 1K.  Utilizing a 1K fiber that’s three times thinner than Kevlar, this TENSEI is billed as the most consistent yet.

The Mitsubishi TENSEI Pro White 1K is both instantly recognizable as a TENSEI, but also clearly something different.  What stands out most is the iridescent finish on the TENSEI branding.  This takes a shaft which is largely black, white, and grey and injects it with a burst of color.  The signature “Multi Material” logo also gets this iridescent treatment.

Other changes to the TENSEI Pro White 1K are more subtle, like the “1K Carbon” logo just under the grip.  You may also notice that the base color of the shaft shifts from black at the tip to grey in the middle.  It’s a small thing that adds another layer of visual interest.


One of my biggest questions heading into this test was, “Is the TENSEI Pro White 1K going to feel any different than the standard TENSEI White?”  It took about three swings for me to realize, “Yes, this is a different beast.”

Let me start by stating the obvious: in the grand scheme, the Pro White 1K and the AV Raw White [review HERE] are very similar.  They’re tip-stiff shafts that are very smooth with a little action in the butt section.  That said, the Pro White 1K has more of everything.  When I put a strong swing on it, there’s more action in the butt.  On the other end, the tip feels even more stable.  For me – a player that needs tip stability but likes a smooth feel – this is perfect.

While the technology and material stories are interesting, we play golf to hit shots and enjoy ourselves.  What stood out most to me about the TENSEI Pro White 1K shaft is how much fun it is to hit.  From the very beginning, the drives I was hitting with the Pro White 1K were putting a smile on my face, and I kept swinging long after I’d gathered the data I needed.

That enjoyment came from the combination of feel and results.  I loved having the sensation of the shaft “working,” then looking up to see the ball launched in the optimal window.  With just enough spin to keep the ball in the air, my best drives had minimal curve and seemed to carry endlessly.

Thanks to that combination of feel and tip stability, the TENSEI Pro White 1K allowed for all manner of swings.  I could make an 80% swing and still get a consistent feel.  The super stable tip allowed for the 110% swing, too.  A shaft that can work well with both is a rare find.

The Mitsubishi TENSEI Pro White 1K is available in 50, 60, 70, and 80 grams.  Four flexes – regular, stiff, X, and TX – are offered in 50 and 60 grams.  At 70 and 80 grams, Mitsubishi offers stiff, X, and TX.

After such a glowing review, you might be wondering if the Mitsubishi TENSEI Pro White 1K is going in my bag.  It absolutely is.  The numbers I got from it were sensational, but more importantly I love swinging it, and I have great confidence in it.  If you want to see what the most premium version of TENSEI can do for you, head to you fitter to test the Pro White 1K.

    Did you test other 1K shafts, in other weights?
    (50TX has been loved by other tester…)
    Regards PEO

    Great review, I’ve been waiting for this one.
    Did this knock the Ventus black out of the bag? Or were you in something else?
    Cheers mate

    • Matt Saternus


      I had the Nippon Regio Formula MB+ in the bag between the two. All three are outstanding, and I could honestly game any of them.


      • Great review as always Matt. I game the AV Raw White 65X in a Sim2 after reading your glowing review. This new Pro has higher torque rating. Why switch? The black version seems very similar in spec to the white.

        • Matt Saternus


          I don’t think you should switch unless there’s something you’re unhappy with about the Raw White.



          • Thanks for the reply and advice Matt. I have similar speed and a preference for 60X/TX. I like the automatic power fade I get from the AV Raw White 60X, and we all must be aware of “analysis paralysis” LOL. As you said in your reply, I’m not looking to change, but it sounds like your Pro White 1k does well with the “80% 18th tee swing”. You said it feels active in the handle even with the 80% swing. Question: Is the difference between your Pro White 1k 60X and the AV Raw White 60X negligible, or did you feel like you had to step on the AV Raw a bit more to get it to perform? I feel that my AV Raw White likes all the sauce every swing and one can get late quickly. Thanks for your time.

          • Ryan,

            I think the difference is negligible. If I’m hitting them side by side and really paying attention to the feel, I can probably notice something small, but there’s no way I could tell the difference on the course when I’m actually trying to hit shots.



  3. Matt- With club head speed clocking in at 109, that’s a few MPH higher than your other reviews. Do you attribute this to confidence in the shaft or a change in golf fitness regimen?

    • Matt Saternus


      Neither, I’ve just been healthy for a bit for my speed has ticked up. Over the last year or so, there have been a lot of small injuries that have kept my speed down a bit.


      • im very similar to your numbers, if not exact. yet everytime i get an x flex its too stout for me….for example ventus tr blue 65 too stiff, av raw white stiff just right. Do you think i should order the stiff in the 1k. Getting the tsr3.

        • Matt Saternus


          My advice is always to get fit. That said, it sounds like you know the answer to your own question.



    • Might be the new Jumbo grips?

  4. Luke Richmond

    Hi Matt,

    Great review! What head did use, G425 Max?

  5. Peter Gustafsson

    When you refer to the “Standard Tensei” would that be the Pro or Non-Pro version?

  6. Hi Matt,
    Do you think you would have lost the tight dispersion had you played the S flex or do you think the tip would remain pretty stable at your swing speed?


    • Matt Saternus


      I don’t think 105-110 MPH is going to “overpower” the S flex, but I suspect that I would not be as comfortable with the way it feels.



  7. Hi Matt. Im currently hitting a Ventus black 6x and find to to have almost no feel. My controlled swing is 110 and my all out is 121 to 123 depending on how healthy i am. Wondering if the tx or x in the 60 would suit me better.

    • Matt Saternus


      The only way to know would be to try them both with a fitter. Without that, your guess is as good as mine.



  8. Wow. 1889rpm in a G425 Max head is unheard of. I can barely keep my LST under 3000 and my AOA is +2.
    Going to have to try this shaft.

  9. Hey Matt- I love reading about your reviews! I currently have the Graphite Design XC 7s and the Ventus Blue 7s but am looking for a lighter shaft. I love the stability and the feel of the Ventus Blue. I am currently looking at the Tensei 1k 60s, Diamana DF and Diamana ZF. Any thoughts or recommendations for something else? Looking for Low spin to Low/Mid Launch shaft.


    • Matt Saternus


      You can’t really go wrong with any of the shafts you listed. All of those have been gamers or near-gamers for me. My best advice is always to get a fitting, ideally with a fitter who would have all those shafts that you want to try in the weight you’re trying to get to.



  10. Hi Matt,

    Love all your reviews. I’m ordering this shaft in the 50G and am battling between the X and TX. Swinging at 114 with 170 ball speed, fairly aggressive transition. Any info or advice would be appreciated.

    I’m currently gaming the Cally Max LS with Tensei White AV Raw 60 X (tipped 0.5”). Have been on a steady workout program and have been gaining speeds. My thoughts with continuing training and the lighter 50G shaft that my SS will continue to rise, thus, leaning towards the TX model. Unfortunately, I do not have access locally to try either model.


    • Matt Saternus


      It sounds like you’re leaning toward the TX, and I wouldn’t try to talk you out of that. My experience is that if you play something that any part of you thinks is too soft, you’ll end up questioning it and being unhappy.



  11. Great post Matt.

    I was looking into buying a PXG 0811X after trying my brothers and loving it. I went to my local fitter and he had my try the ping g425 max and loved it even more! I play A lot of best ball/scramble tourneys so I’m looking to build a forgiving Long distance driver when we my team is really kranking drives.

    What degree g425 did you use and was the shaft cut to 45”? I was thinking about doing 9.5 degree with stiff 46” length. My local fitter has limited weights in 1k vensei.

    I would love to hear what your thoughts are before settling on the limited selection 1k shafts that I will be testing out next week.

    Much appreciated!

  12. Jeff Eddins

    Looking at the tsi driver line, demo’d the yellow smoke in it, good numbers, but I really like the feel of the av white, but need a little less spin. Do you think the 1k spins any less than the original white? Thanks!

    • Matt Saternus


      I think it’s possible that the 1K will spin a bit less, but that will vary from golfer to golfer.



  13. Hey Matt,

    Always love your reviews and your descriptions are usually spot on. What driver head did you test this shaft with?

  14. My H speed 90~95 . I was using X s …but getting old every year my H speed down side….you think I have to using R 50 ??? Please 🙏… can you tell me.

  15. Great review as always.. was wondering if this shaft had boardy feel.. or really is smooth as advertised. thank you

    • Matt Saternus

      “They’re tip-stiff shafts that are very smooth with a little action in the butt section.  That said, the Pro White 1K has more of everything.  When I put a strong swing on it, there’s more action in the butt.  On the other end, the tip feels even more stable.  For me – a player that needs tip stability but likes a smooth feel – this is perfect.”

  16. I’ve always been more comfortable with blue profiles, and my GD AD HD has been a phenomenal driver shaft. But as I’ve added speed, launch and spin are getting high, and an offseason goal has been bringing both down. I’ve been demoing things here and there, and I liked the Ventus TR so much I bought one and threw an All-Fit adapter on it.

    … But the 1K was a revelation. I hadn’t even bothered with it before, because I knew the profile on paper wasn’t for me. I got a chance to hit 100 or so balls with a 1K 60X today and it was just on cruise control. 166-168 ball speed, consistently hitting the window I’m looking for, and your review is exactly right about keeping that nice feel even when you don’t go after it. Part of adding speed has involved a tempo change. Today’s experience has me wondering whether I’m moving toward a different profile with the new tempo … or maybe it’s just the 1K specifically.

    One head-to-head I’d be interested in trying is the 1K vs. the GD AD XC. On paper, it seems like the 1K would have a slightly softer butt and stiffer mid and would feel more one-piece vs. the XC having that Graphite Design kick, just higher toward the handle than in most of their shafts and maybe less intense than most of their shafts. Matt, I know that XC review was a few years ago … I assume it’s probably been too long since you demoed the XC to offer much in the way of comparison, right? Not sure if the feel is still clear in your mind or you’ve had a chance to hit it since then.

    • Matt Saternus


      I’m glad the 1K worked well for you.
      You are correct, my time with the XC was too long ago for me to confidently offer a comparison.



  17. Hey Matt,

    105ish swingspeed… picked up a 1K 50TX coming from a RDX Black 6.0 that gets just a bit too much spin, what should I expect to be different?

  18. How do the flexes compare between the Tensei AV Raw White vs White 1k?
    I’ve heard the AV raw 65S feels slightly stiffer than the 60S 1K, and based on specs the torque is lower on the AV Raw.
    It appears that the 70S 1K would feel more stout than the 60X 1K based on torque and weight, does that make sense? Thank you!

  19. hey do you think the 60x could handle a little more club head speed. I’m at about 112-115.

    Was looking to see the difference between TENSEI 1K White and the TENSEI 1K BLACK? But there is no black review on site?
