I see about as many CF shafts and wood shafts in my shop, so they are far from indestructible. If you go back and listen to the original promo video Predator made for the Revo line of shafts, Pia is basically just parroting those claims, so this is nothing more than marketing in a more personal form. The constant comparison to tennis rackets, golf clubs and hockey sticks is a bit dishonest, as none of these pieces of sports equipment have a high focus on feel and feedback. I think a more fair comparison would be instruments where feel is essential and if you have a look there, Carbon fiber has made very little inroads in the music instrument market..
If you prefer wood or carbon fiber, they both have advantages and disadvantages, saying categorically that one is better like Pia (and Predator) does is just not true. It really depends on what features you emphasis.
