I use the QAD on my Commander and love it, robbed it off my Old Glory before I sold it actually I liked it so much. The RipCord is pretty much identical, except you can't let down with it and have it stay up, so the QAD is better there. Limbdrivers are pretty sweet, but you will need to put some other form of containment on your shelf to keep the arrow there, so the QAD wins again IMO.
