RE: More bow tuning - level nock travel
Fritz,
Your nocking point and "level nock travel" are not the same thing. There is only one optimum nocking point on your bow. You would attempt to find this by having your shaft bisect the berger button hole and then moving the nocking point up or down until you get the best horizontal grouping when tuning at a couple of different distances. With your nock in it's optimum position, you still may not have level nock travel. That has more to do with the bow and cam design.
