I can't give you advice about the Muzzy rest but I just bought a
Ripcord fall away rest. The archery shop owner, where I just bought
my new Switchback, suggested it. I had asked him about the Whisker
Biscuit and he said that the Ripcord is hands down a better rest, less noisy, more accurate. I have had this since last Friday and have shot it all
weekend. All I can say is so far it works for me.
