Well, I'm probably the drop away nut on here. I have played with the MZE, the Trophy Taker, the NAP 4000 drop away and the DropZone.
Here these are in order from my most liked to least:
NAP 4000 (solid, flawless performance. I am not getting rid of it. Its is now affectionatly referred to as Ol' Faithful

)
Trophy Taker (currently tinkering with and its a tack driver so far)
MZE (one of the best I've used, except it makes your life difficult getting a quiver on it.)
Drop Zone (was a little heavy and bulky for my likes. If they would put that rest on a diet, I would probably buy one again to try)
