What should i shoot carbon or alimiun i shoot alimium right now and shoot good but i hear a lot of hype on the carbons.

Try doing a search on this board for carbon arrows, theres been alot of talk just recently, you may find some information in the older post to help your decision.

It took awhile to convince me, but carbon is the way to go. Faster, lighter, stronger...

They are pricey, but unless you end up Robin Hooding a bunch of arrows, the typically last a real long time. If you go that route, take the trouble to go to a good archery pro and have him set you up. Typically he' ll have you shoot thru paper to make sure that the arrow chosen is the right one, given your draw weight, type of rest, etc.

I switched back to aluminums this year. For me they just seem to shoot better.
You will get more speed with carbons, but speed ain' t everything!
