A 60 pound bow you can shoot accurately and handle easily in the woods is a lot more deadly than a 70 pound bow you struggle with and can't hardly shoot at all.25 ft lbs of KE stuck in the heart/lung area is a lot moreethical than 90 ft lbs stuck in the guts.

This ain't no chest thumping macho man exercise! Shoot the draw weight you can handle, make intelligent choices on arrow weight and broadhead type, make sure those broadheads are shaving sharp and hunt within your limits. You won't have any problems.
