I have been using the Muzzy rests since they came out on 3 different bows, 2 of them with the roller guard. I just put one on my new Switchback last week. If your threaded rod that attaches to the cable is torquing badly it is NOT set-up properly. That threaded rod should remain straight and should not bend during draw. It sounds like it is not timed properly. The cable connector should be 3.5 inches from the bottom of your roller guard to the center of the screw that connects it to the threaded rod. Once that is set then you time the rest by controlling the length of the threaded rod. Adjusting the length of your threaded rod will eliminate the torquing that you are seeing.
