If you want a true full containment rest that is simple, look at the APA Twister Safari rest. I've been using one for about 3 now and don't see putting a different rest on my hunting bow anytime soon. I still can't believe this rest hasn't been popular for hunters. Full containment and microadjustability. One of the really nice features is that the cord can be adjusted at the rest to set the timing.

It's been on 3 different bows for me so far.
