RE: QAD HD Rest setup
Most of the guys have covered it. I can add that I've used the clamp and the cable through the string and I prefer it through the string. Reason being is as you know in PA we've got more than our share of vines and stickers. They always seem to find that cable and I can tell you I got to my stand more than once and had to pull some thin vines out of the clamp. It also had me wondering if it got moved. It never did, but it's one more thing to worry about.
Great rest though. You'll love it.
