It's degenerate. I stick with 60# as it it still over the recommended kinetic energy by like 15 ft lbs(correct me?) of what is needed to kill a Brown bear. BTW; I would still be shooting 70# bowsif it weren't for Huntnet and Archerytalk and what I have learned. Try reading up on the subject instead of remaining ignorant on the subject; that's what these forums are for.
