I've been shooting carbon express terminator selects (45/60) at 9.5 gpi. I'm going to try the gold tip xt (55/70) because they are lighter- 8.2 gpi. I have shot Beman ICS hunters and blackhawk vapors. The blackhawk vapors would be my second choice behind the GT's, but I'm concerned about their durability. Three of the blackhawk vapors have split near the insert. The weight of the vapors (7.9) is what I really like. The terminators are good just a little heavy for what I like. I can't comment to much on the bemans, as they were my first set of arrows, and lost them. Additionally, because of the price now-a-days I wouldnt shot anything greater then a .003 straightness.
Just my .02 cents worth.
