I can pull 70 pounds very comfortably sitting down with my legs crossed in full camo. I would also shoot 100 pound bow if I could do the same with a bow of that weight. If you can pull it and hold it for about a minute with out shaking and are accurate with it then shoot it. It gives you just a bit more power that you might need someday for that shot that wasn' t perfect or that monster elk or moose..
