Lx, you just opened up a huge can of worms with this one.

I have used the NAP Quick Tune 4000, TR Drop Zone and currently use the QAD Ultra Rest. I have also setup a Trophy Taker on my friend's bow. I think all of them are very nice. The QT4000 is probably out because it uses a cable slide as does the Muzzy ZE. I picked the QAD because of the total containment it offers. I don't have to worry about my arrow falling off of the rest when stalking or drawing back. I had to increase the spring pressure to make sure it moved out of the way faster but that only took 20 minutes.
