You do know that unless they are cnc produced every grip will be slightly different , this is true no matter how many bows a builder builds , However not all bowyers are created same when it comes to wood work and the craft of shaping. some will get it more consistantly close than others. However they may feel slightly different;
I just delivered two Eaglewing reverse mounted bows to a customer that were to have identical grips. I did the best I could and he says he is more than happy with both but likes one better than the other. SOOOOOOOOOOOOOOO thats my story and I'm sticking to it.
God bless you all, Steve
