And I' ve done things with an aluminum arrow where the same hit with a carbon caused the carbon to disolve in a cloud of black dust. True story! A guy shooting a Beman hit the same overhanging limb I stuck a 2216 into, not an inch from my arrow, and his arrow exploded. It was kinda cool... Black dust that glittered in the sunlight.

My 2216 was in perfect shape and I shot that same arrow the rest of the tournament.
The real killer though was, for the entire shoot up to that point, the fella had been going on and on and on about how much flatter carbons shoot and how much tougher they are than aluminum.
Truth be known, it could have just as easily been his arrow that survived when mine could' ve been cratered, but the Fates were on my side that day. The explosion was very effective in shutting down his flapping piehole, and I enjoyed the moment immensely.
Carbons are more resistant to many minor clinks and clanks that can mess up an aluminum arrow, but when it comes to massive collisions, neither kind is better than the other. I' ve destroyed quite a few of both. Had some hits where the arrows weren' t phased when they should have been toast and had some totally wrecked on hits that I expected them come through without a scratch.
Durability would be a SLIGHT edge to carbon. Compare durability between carbon and a similar weight aluminum, and carbon' s edge gets a good bit wider.
