Just picked my bow up at Lens. He changed out the string and cable on my liberty. Took home and shot thru paper high tear, adjusted the MZE to come up higher, and lowered the string loop about 1/16" inch, bam, shooting bullet holes thru paper. Go out in the yard, and mount my montecs, shoot at 40 yards. Made a slight adjustment and now broadheads and field tips hit together at 40. This is the way tuning should be.20min. I deserve it. Last two bows, I have worked on have been a bear.
