Actually Nord, I think Arthur may be right when he says "...you won't see much difference in durability between a heavier aluminum shaft, like the 2216, and carbon ". I'm ashortdraw and only pull 56# so consequently the aluminums I use to get the spine I need wind up being much less durable than a 2216 would be. I even shot 2013's for a while and I could bend them simply by pulling them out ofa strawtarget.Anyway my experience in switching may well be much different than yours. I'd say try some and make up your own mind.
