I' ve switched back to aluminum from carbons! I' ll be using the Easton XX78' s!
Speed alone is highly over-rated! Speed is so popular these days, the guy at my bow shop thought I was crazy for going back to aluminum arrows!
With my setup, I could be shooting 300 FPS, but I' ll gladly sacrifice 40 FPS for the added accuracy and quietness that I' ve got now!
