I don't know about that. I think with the differnce in flex points and tourque each shaft does have the potential to give you more distance once you find the right one for you. I had the same driver with a Graphite Design 6+, Aildlia NV, Fuji Speeder and now an Accra Tour, why am I getting more distance and accuracy with the accra than with any of the others if no one shaft can make you hit any further? You still have to put a good swing on the ball don't get me wrong but each shaft with its flexing properties will give you different distance and accuracy, I've seen first hand. As for the projext X's, yes there is marketing hype, but these shafts are not on every commercial yet many tour players and amateurs play them. Their technology is very different and they have been an industry leader in the whole FM thing IMO, that's why I am surprised that these shafts would not be as well, wait and see.........
