RE: Cannot tune out Nock Left Tear
Hand torque.
Change your grip a little to see if that helps. Normally a right handed shooter that can't get a left tear to correct, is torquing the bow.
Provided your arrow is adequately spined for the lbs. you're shooting.
Cam lean would be another option to look at.
Make sure your form is correct, including your bow hand, never gripping the bow, even slightly. Relaxed bow hand solves more problems than trying to change equipment to correct problems.
