Jeff i have a di95s that plays 40.5 in my 18 hybrid.
Have used this same shaft and reshafted several times but to no success
This sucker is so stiff and plays stiffer than my steel stiff shafts. In fact
It weighs the same as my nspro 950hybrid but feels loads stiffer.
I would have preferred a di85s hybrid, the 95launches so damn low too
