I don't think the problem is that predator doesn't care, its all about marketing something that can be subjective depending on testing conditions.
If predator comes out and says that the revo has .5" of deflection, another manufacture will vary the test varibles a little bit (say hitting slower) or exaggeration of the swerve effects and say their shaft only deflects .35" and therefore is better than the revo.
These carbon fiber shafts also have a semi implied no deflection marketing to them, which we know isn't 100% the truth. Putting a deflection stat on a shaft that's implied to be no deflection doesn't make any sense.
Well, sure. While I don't disagree with any of that, can all of that not be said about any competitive product whatsoever? Data sheets are still given out by most manufacturers in much higher competitive fields, so why not for this? Besides, we're not asking for the formula to resin and carbon fiber, we just want plain basic dimensional measurements that can be determined by just about anyone willing to destroy 2 shafts.
So what's there to hide, or better yet, what's there to gain? The only answers I keep coming back to is that they simply don't care or that they really are hiding something they shouldn't be, but the answer is most likely the former. No matter what though, in the age where becoming more transparent in increasingly relevant, Predator is most certainly one company who isn't interested in transparency.
