Correct, yes carbon arrows are more durable as far as denting aluminums and they certainly are less likely to "bend"....

I personally currently shoot Easton Acc's...over the years I've shot XX75's, XX78'd, Beman Trophy Hunters, Beman ICS's, ACC's, Back to XX78's and back to ACC's....they all work great....carbon take more abuse...I feel ACC's are superior.
