Get game getters then. Fairly cheap with great tolerances. Also the larger diameter shaft will help with contact problems with your prong rest.

When comparing cheap carbons and cheap aluminums the aluminum arrow is almost always the better way to go as far as quality control and consistancy from arrow to arrow. There are some very nice carbons on the market, but they are not cheap by any means. The good thing is the arrow companies know this and they get better every year.
