S2S Black 65 & 85 Wood Shafts


S2S Black 65 &  85 Graphite Shafts for Woods

TWGT’s Graphite Design for Better Golfers 



  • S2S Black Graphite Shafts are created with an improved, slightly stiffer tip bend profile design for golfers with Transition/Tempo/Release ratings from 2 to 3.
  • S2S Black 65 gram Wood Shafts are for golfers with more aggressive swing characteristics who have a Strength rating of 1.5 to 2, OR who may be stronger but simply prefer the lighter total weight feel from a 65g shaft weight.
  • S2S Black 85 gram wood shafts are for golfers with more aggressive swing characteristics who have a Strength rating of 2 to 2.5, OR who may be weaker but simply prefer the heavier total weight feel from an 85g shaft weight

  1. Tom,
    Thank you in advanced for your response.
    I have a stock shaft and head from a big name brand that performs excellent for me. I would love to match or profile some shafts for the future.
    How would I go about matching the shaft with another? I do have an auditor shaft profiler that I havent used yet. Dont know if that’s helpful.
    The shaft already has an adapter on the end and a grip as well.
    Is there somewhere I could send it to get it profiled?
    Any help would be much appreciated.

    I have already done a guess and test of several shafts but nothing perfect yet.
    It’s not hard to match the weight, it’s the bend profile that’s difficult.

    Could I use my auditor shaft profiler from golf works to coincide with your profile method and comparison charts?

      Not an easy answer and one that you might raise eyebrows at because no one wants to disassemble a club they presently hit really well for fear of never getting it back together to perform exactly as now. But that is what you would have to do to profile the shaft precisely enough to know more exactly what other shaft(s) might be the same or similar enough to play the same for you. With the bare shaft with no epoxy in the tip or tape on the butt you would then have to do zone frequency measurements with the Auditor under the same protocol as what we used when we were supporting the Wishon Shaft Bend Profile software and its data base. That would require the Auditor to have a special chip in the board that increases the top CPM reading to 1000cpm. If you have a standard Auditor it has a ceiling of 600 cpm which is not nearly high enough to do zone freq measurements of shafts all the way down to the tip half of the shaft. Second if you did have a 1000cpm Auditor you would then need a 454g tip weight to do the measurements. That’s the standard upon which all the shafts were measured that are in the Bend Profile software data base. And then you’d need the Bend Profile software to be able to search for shafts with the same or similar bend profile and that’s also tough since a boycott by the shaft companies killed the annual updates to the data base. You’d likely have to search down a clubmaker with the software on his computer and have him do the search once you gave him the zone frequency measurements you would measure on the shaft(s) from your clubs. Long story on that one not worth repeating right now. Now with all that I would have a question for you – why would you want to search for other shafts that might be similar? Since you found a shaft you like a lot it would stand to reason to just stay with that exact shaft, trimmed and installed the same way these are. That’s a whole lot easier if the goal is just to duplicate the shaft in these clubs. The other elements that contribute to why you like the clubs so much have to be measured separately and accounted for as well – length, total weight, shaft weight, balance point, head weight/swingweight, MOI, grip type and size. Hope this helps,


  2. Hi Tom,
    Do you know which of your current shafts is must similar to the older Wishon Interflexx High-Launch S flex? Interested both in weight and bend profile.
    Thank you!

      Sure thing, the closest to the original Interflexx High S would be the S2S White S. The butt stiffness and the tip stiffness are very close to the same in the White.


  3. Hello Tom,

    I’m from Korea and I appreciate on all of your work.
    I learned a lot of things from your youtube and website.

    I’m surprised on this shaft spec because 65-R&S CPM of 36″ to 16″ is higher than 85-R&S. Is there any reasons for flexible mid section of heavier shaft?

      Thank you very much for your post and your interest. We appreciate that very much. I am sorry but the bend profiles of the 65 and 85 gram versions of the Black shaft are supposed to be the same so it must be an unfortunate miss print of the bend profile specs in the catalog or website where you saw it. I will need to tell Diamond Golf to be sure to correct that for the coming year. Thanks very much for letting me know.


  4. Hi Tom,
    Thank you for all you do for us mortals…I enjoy reading your posts and books. I have learned alot. I’ve had good luck with the Ping Tour shafts in drivers (both reg and stiff). Does your database show how these would compare to your Black…or is it more close to the white? Thanks again.

      Many thanks for your very kind words. Let’s just say I very much appreciate that you appreciate what I try to do to offer good, truthful information to help you enjoy this great game a little more. Thank you! The collection of OEM company proprietary shafts in the bend profile software data base is very limited because we are not permitted access to those shafts by any of the companies. Nor can the shaft makers who manufacture them send us samples to measure. The only OEM shafts we have in the data base come from clubmakers having submitted the shaft to us after they did a re shaft for a golfer and removed the shaft intact. So it is limited. Wish it were otherwise but the big companies just do not want to support our desire to offer bend profile data for making shaft to shaft comparisons. So I am sorry but I can’t answer your comparison question.
