Sorry, I've only shot the QAD, but I know the Ripcord is similar. I read the "test" in Bowhunting World magazine, and also read that the Ripcord is supposed to be quieter. I would add that my QAD makes very little noise. I took a GKF 3D Royal off my Darton Tundra to put on the QAD, and the QAD was much quieter, no comparison. I am also very pleased with the tunablilty of the QAD, and the accuracy I'm getting. To be perfectly honest though, I'm shooting virtually the same with my backup Rampage with a Starhunter rest, as I am with the Tundra and the QAD.
