I guess my main reason is that I have never been told a good reason to switch. I am not a speed freak, could care less about speed.
Plus, I have never liked the warning that accomponied the carbons. You know the one that says if the arrow breaks don't consume any meat from that area. Why would I want to throw away a nice piece of shoulder meat because of carbon splinters. I know, I know....it takes a lot to break them, but you can't tell me that it don't happen.
