Nock tuning is another solution for this. I shoot groups and paper tune bare shaft (rub a magic marker on your field point tip if you have issues deciding what end of a tear is tip and which is tail), turning the nocks an eighth at a time until I get the best groups with clean tears. By doing this, I can tune my arrows to my bow first, rather than trying to tune my bow to my arrows.
