As to be expected in generic stock shafts, these diamana's have close characteristics to the real ones. Titleist has used its own developed specs for these which slighty vary from the actual diamanas.

This is the real Diamana with a slight modification. The torque rating is slightly higher in the Titleist version. The non Titleist versions have a torque rating based on the x-stiff shaft. Titleist did a lot of research and found the average golfer needs more torque. 

If you are getting the x-stiff Titleist Diamana then you are getting the same shaft characteristics as the real Diamana. Only the stiff and regular have the torque changes.

Thanks guys!

I just put in an order for 910 D3 with Diamana Ahina x-stiff.  Can't wait!!!

i just received word that the order i placed (910 D3 with the real ahina white board will not be available until april, decided to go with the Xstiff titleist ahina, changing from a 909 D3 with a fuji 757 X.
