I'm still trying to find my own setup. If you read thru the forum here, you'll get a lot of opinions about the best arrow and such. Most folks say one is better than the other b/c they've killed game with their setup and they have confidence in it.
You'll have to experiment and see what works for you. I've shot them all and they all fly and will kill game. I switched from aluminum to carbon then to hickory shafts. My reason is that I shoot a 70# + pound bow and with hickory, I can get my arrow weight up to 750+ gr without front-loading and arrow. Not that front loading is bad, I just haven't made it work for me.
They all break (bend for alum) at some point or another...If you have to straighten a wood arrow, it isn't that big of a deal. Its not like you have to straighten wood after every shot. Just check them once in a while.
