You don't want to change your nock point because you change your rest. You adjust the rest to your current nock point. If I was you I would put the new one on and I'll bet your groups close up. I have never been a big fan of those biscits, especially after there worn a bit. Changing a rest really isn't that bad, eyeball it close and then micro adjust it up or down and left and right without changing anything else. Use your 10 yard pin to dial it in. Then once dialed in you might have to move your other pins a little. Where all here to help ya out............
