Black Frog, I was referring to repeatable nock travel. BTW, congrats on some fine shooting lately.
Nearly anything that is repeatable can be adjusted in some way to be acceptable and useful. Obviously the more issues there are to correct, the more work there will be involved. Some may not be adjusted to total satisfaction, or the particular form of an individual may not meld well with a certain setup. But, regardless of nock travel, single cams, dual cams, and hybrids can be made to shoot better than we can. Hasn't this been shown by bows with everything against them putting arrow after arrow into the same hole, when shot from a machine?
