I have sold used and setup many drop aways including but not limited toQAD, Ripcord, Muzzy ZE, & Limb Driver.
All things considered the Limb Driver IMOis the best all around drop away on the market.
Ease of setup, no timing issues, and/or resulting fletch clearance issues. Unless you stand on your head in a Treestand I can't see full containment as a viable issue. I have hunted several hundred hours in the last couple of years with a limb driver in winds up to 40 mph and have yet to have my arrow blow of or any other issue. I can cant my bow 90 degrees and my arrow still stays put.
