I shoot a pse bruin with a loop release. I have shot it for 3 years and never got it togroup very well. But anyway the top of my loopis wearing more than the bottom. Could this mean that my rest is to low which wouldmake the loop to low causing the top to wear more? I really don't know it was just a thought.. 8-1-06 got a new loop and new rest today (trophy taker ) groups much better with this rest. It beat the WB easy .
