That's because the bow is torque tuned, not because of the design. Has to do with setting sight and arrow rest position for maximum forgiveness.A friendly fella at an indoor tourney showed me once where he could twist his grip with his Prime and the arrow still hit where he was aiming. it was pretty cool.
I beat him by 5 points and 12 x's. I wasn't shooting a Prime. Weird huh. :wink:
