I shoot carbons too - after 20+ years of shooting aluminum. I've been considering going back someday to aluminum for some of the reason listed.
Here's a link to an article on this very subject written by Chuck Adams. Another HNI member posted this in the bowhunting forum, so I can't claim credit for it. It's pretty informative. Realize that Chuck gets all of his arrows free from Easton and is a paid spokesman for them, but I still value his opinion. It's a good read.
