Ive been paper tuning my z7 with that new mathews grip. I have managed to get a bare shaft to tear about 1/4 in high 50% of the time and with no problems left and right at all. the other 50% of the time it tears about 1.5in high. Im pretty sure that im putting different pressure on the grip. My question is if I put either a low wrist or high wrist grip on will this correct my problem?
