Too many things to go wrong with a drop away in my opinion. Creep 1/8" of an inch on the shot before it breaks which happens a LOT when you have bad footing, etc........and now your rest is moving. If you don't setup a cable driven drop away so that it's hitting the full up position in the last 1/2" of draw then it's wrenching on the cables changing cam timing. Too many variables for me, and a spring steel type of rest doesn't have any of these issues, it just works.
