Personally, I switched from the ripcord to the QAD rest. One of the main factors then was that the rip cord would not stay up when you let down the draw. It would fall too. The QAD, by design, would stay up and keep the capture on the arrow.

However, this is one of the problems I'm having now is that the QAD will not remain up on let down and will occasionally fall all on it's own.
