My two pieces of advice would be to look at "Stu's spine calculater" program that's attached to another thread going on right now. It's probably one of the best tools out there for getting you close to the right arrow fit for a type of bow that I've seen. The second is that if you're looking at carbon arrows, I'd recommend the Easton Axis line. I've tried Arrow Dynamics, Grizzly Sticks, Vapor Carbonwood,and Beman MFX. The Easton Axis, front loaded, is the best hunting arrow in my opinion.
