RE: It'll be a cold day in he....
I converted to Carbons 3 yrs ago (Carbon Express CX-300's); bought a dozen. Still have 7 of those original 12 left. Robin hooded 2 of the 5, lost 2, and had to snap one off when I buried it into the frame of a target. BTW, the one that I had to snap off, I had to jump on the thing to get it to snap (this means sideways pressure on the shaft here folks, not straight on).
I have no doubts in my mind that I could smash right through the thickest bone, and the shaft would come out the other side untouched.
I think what Easton and other manufacturers of Carbon shafts are doing is placing a nice little cover over their a$$ in case of any potiential law suits....
Ever try to break an aluminum shaft over your knee? Try the same thing with a carbon shaft - lots more effort to break the carbon...
