Can't say I've seen them bend from shooting although I'm not too thrilled with them right out of the box. At least the ones I've checked. Just one reason I won't shoot them.

On the other hand, these and any other carbon can take a bend if you twist them to remove them from 3D targets. It breaks down the bonding of the shaft near the point end. Usually within 3-4" from the end. Had this happen with ICS arrows a few years ago.
