Like the Quicktune 1000/3000 or the Bodoodle? One thing right of the bat I noticed with full containment rests like the WB or fallaways is their lack of "tunability". I don't think I've ever spent so much time tuning than I have than when I started using fallaway rests. I'm truly thinking about returning to a prong style shoot thru rest. I've never had issues with those "old style" rests.
