I would figure out what spine you need and then spend the extra doe and go with carbons, such as the GoldTips mentioned above, I shoot carbon express myself, but again, I am sure the GTips are just as good.
I shop aluminums for years until someone here at tradgang turned me on to carbons, I have saved a fortune in arrows since then as the aluminums were constantly getting bent, and I was shooting the better ones. Not to mention always having to check them to see if they were straight after each practice session, then constantly straightening them when possible.
You will have to check carbons to make sure they don't have any cracks after every shoot, but I have only had one crack in 2 years of thousands of shots and that only because I dropped a shot short while stump shooting and hit a huge rock! DK.
