I am trying to bare-shaft tune the WB delux after noticing a slight nock-high tear with fletching. After several shots with a bare shaft at 6 ft, I have a moderate nock-high tear. I can't move the rest any farther up, and I can't seem to move my string loop to change my nocking point. Can I make slight adjustments to my tiller (tighten the bottom limb) in order to bring the nock point down without any adverse effect to my bow's performance?
