I tried the HD which is essentially the same. I had issues with it on my BowTech with it tweaking the down cable and effecting the tune of the bow. I don't think that's a problem of QAD's though, I think it's an '06 Binary Cam issue. Otherwise I think it was a great rest. The only thing I would like to see improved on it is a metal launcher instead of plastic. I just don't trust plastic parts in cold weather.
