OK, I looked up the Game Master II. I assume the Game Master is still an alloy riser... these guys are cut past center and are designed to shoot with a screw in elevated rest from what I can tell so you are real close to center shot depending on your rest. This means, if I remember it right, you need a bit more spine in the shaft.
That being said.. I agree with Kirk and Lowell. However, this may depend a bit on what type of rest you are shooting and where it is set.
So, what kind of arrow rest are you using and where is it set in relationship to dead center of the riser?
