I have shot both alum and carbon and currently shoot cx and I am very pleased with them,I am sure the others are very good too.If you decide to shoot carbons pick one that your bow likes and what I mean by that is go to a pro shop and get them to let you shoot some of each they have to offer and pick one that shoots the best with ur setup,don't be cheap buy the best you can afford,remember that your arrow and broadhead are the bussiness end of the deal and besides most carbons can be shot for years if you takecare of them.I usually buy a dozen and keep 6 for just hunting and the other 6 for shooting in the backyard.
