I think it is close. I like them both and have shot both thought the years. I have watched as both types exited out the far side of deer and coyotes. I currently use Carbon. While I do not have data I feel I damage less arrows using carbon while I practice and shoot 3D. I worry less about someone else pulling my arrow using carbon. I feel more confident shooting them so ifthey were exactly the sameI would continue to shot what I felt most comfortable with.

A good warning I on one of the previous post, If you suspect a carbon arrow is cracked even a little stop using it. Sometimes you can twist the shaft slightly or tap on it and hear the crack but if you think it might be STOP and get another arrow.
