I used the NAP QT4000 on my old bow and I liked it a lot. It was easy to setup, quiet and never gave me any problems. Unfortunately, it didn't fit my new Defender so I bought a QAD Ultra Rest. That is a very nice rest. You don't have to cock it every shot since the cord will pull up the arms and cock it when you draw. If you do cock it, it has full containment so your arrow won't fall off. It falls fast enough for my bow after I adjusted the internal spring. The one thing I did do for it was take one of the Limb Saver grip insulators, cut it in half and stick it on the shelf where the arms hit it. Now it is nice and quiet. The Rip-Cord uses a similar concept but you can't adjust the internal spring.
