As far as the left tear issue is concerned on the SB, it is an easy fix! The idler wheel is leaning slightly, so no matter how far you move your rest the tear stays. Draw the bow and have someone stand behind you. They can tell you which way the idler is leaning. Then press the bow and give the opposite side split cable a couple twists and check it again. Do this until the idler is straight at full draw and try the paper tune again. You will have bullet hole very quick!!
