You can bet I'm carrying a set of rails and a treestand with me, too, cause I don't sit in trees 6 feet off the ground..my butt is gonna be at 14 or 15 feet.
I shoot heavy bows, heavy arrows so we won't be worried about penetration- except a set of bear teeth penetrating my fanny...so higher is better in that regard. Make him work for his supper, if you know what I'm sayin'.
