I've been looking @ a Callaway Diablo Octane. I know that the "made for" shafts are made to fit a wider range of people (or at least that is what I think I know) so my question is where the heck can I find specs for these shafts and how do they measure up to the real aftermarket shafts? In this case I am asking about the ProjectX 6.0 w/ the Callaway label that's stock in the Diablo Octane -vs- the real 6.0. If anyone has any actual experience with it it'd be great to hear your feedback.
