I guess maybe I'm crazy too, but the best carbons I've found for the money are the Easton Carbonaero Epics that I'm currently shooting. I shoot at 65 lbs and 29" so it's very similar to your setup. I haven't had any problems with durability but I haven't done any stump shooting either. I'm not sure how well any arrow will stand up to consistant impacts with solid objects like stumps.
