While the QAD is a good rest it has timing issues more times than it should and can be a PIA to install.
IMHO there is not an easier, more effecient working dropaway rest than the Limb Driver. I've had 3 on countless models of Bows, and hunted with one for going on 3 years.
I have yet to experience any kind of an issue
