Here I am out of the norm again.[&:] With a rest that has a solid right side (one that will not move, unlike a cushion plunger) set the bow up at centershot. I'm using a fall away that is set up dead on centershot. I check centershot by shooting between 10-30 yards every 5 yards. If you make a C shape with the arrows, your rest is too far out. If you make a backwards C, your rest is too far in. Since I have gone to a rest with a solid right side, the need to set the centershot out has been gone. Thats what I'm doing these days.
