The big issue here will be weight.  The after-market version of the Diamana Blue 63 is lightweight (63g Stiff) and lower-mid torque.  The Titleist Kaili 75 (74g Stiff) is a similar shaft to the 63s but its weight might produce different ball flight for you (lower with less spin).

The torque and flex points are similar but the weight could be a big factor here if you prefer the shafts in the 60g range.

Hello, I would like to ask (sorry, maybe quite a similar question), how big difference is there between the diamana shafts original versus titleist made in the same weigt range. For instance original kaili 60 vs kaili titleist 65 (they weight is quite the same, but the original version has lower torque and higher kickpoint). Is the difference really significant? I am thinking about purchasing D2 with a stiff shaft and I am little worried about too high ball flight (which I am suffering of right now with my X driver and regular flex shaft.). Maybe the ahina 72 or RIP would be better for me from this point, but I am affraid this shafts wolud be maybe too difficult for me (HCP 17).  Do you think kaili 60 gives an advantage compared to kaili 65 titleist? What do you think about the ahina 72 shaft, to which type of player would you recommend it? Thank you very much and sorry for my english:-) Roman Stipal
