to me it doesn' t matter ,my old bow is 65% letoff , my new one is not it' s 75% i hunt to enjoy the great outdoors and for the meat you can' t eat antlers no matter how big they are , and to me a trophy is any game take by rules of fair chase be it a doe or a spike , not that it wouldn' t be nice to take a giant racked buck, all that and beside the fact that my shoulders are bad and i' ll be lucky if in a few years i can still shoot a bow so the letoff doesn' t matter to me!
