resighting with Fallaway rest I recently upgraded from a whisker biscuit to an "Allen" Fallaway rest on my bear compound. I found it shooting down and to the left so I tried resighting it. The aperture is now at its max adjustment with the arrow still off by the same amount. I assume this is because of the rest. I've adjusted horizontal but the mount won't let me adjust verticl without adjusting the length of the rest string. Suggestions? Back to the bow shop who installed it or am I missing something?
