I shot wood and some aluminum most of my life. The old carbon arrow concerns are still around, but are not necessarily true of the better carbons on the market today. The newer carbon arrows don't have the same problems as the old ones, namely inconsistent spine depending on how the arrow is rotated, inconsistent weight, and splintering inside an animal. In a quality carbon arrow these problems have all but disappeared. Are they as straight as aluminum? Maybe not yet. But how many can shoot the difference? And if you can, how much of a difference does it make? For a traditional archer/hunter the difference (if there is one) is negligible.
This is not my opinion, this is a statement I heard: According to Rod White, Olympic Gold Medal archer, only world level caliber archers can shoot the difference between .004 and .001. I've offended a few guys sharing that statement, but I'll take his word on it since I sure can't shoot the difference. I don't mean to offend anybody on here who disagrees, but I share that because I think it is relevant for the average trad hunter.
I'm not trying to sell anybody on carbon arrows by any means. I have only killed two big game animals with a carbon arrow and a boat-load with wood. I don't think I'll ever shoot aluminum because I see no advantage (for me) over carbon. I don't like messing with straightening an aluminum arrow, and I bend them too often. It is easy to get a carbon arrow up to whatever weight you want to if you so wish, so the weight advantage that aluminum used to enjoy is no longer as big of a concern. I never had to re-fletch my wood or aluminum arrows because they broke or bent before I wore out the feathers. But I've got 7 out of 12 CX Heritage carbon arrows left from 1.5 years ago. I have re-fletched them four times. I lost 5 of them but haven't broken one yet, and they definitely don't bend or warp.
I love wood arrows and though I've been shooting carbon the last year and a half, mostly for convenience sake, I plan to go back to my woods. It's the process of making them I think that I enjoy the most.
They're all good! I say to shoot what you have the most confidence in, or what you can get to fly the best for your setup.
