I ordered my last bow before my shoulder surgery to max out at 60 pounds. Now I'm completely recovered from it and found that I like it so much I'll never go back to a heavy poundage (70-80) bow. It will do anything I'll ever need to do with it. If you could move up to a 50 pound max bow,that would easily kill a whitetail within any reasonable range. And the razorcaps are only 1 1/4 cutting diameter and come in different gr too. But I will say that a smaller 2 blade cut on contact will penetrate easier and thus deeper,but not by a lot.
