I have used three fall aways. The Trap Door, MZE, and the Trophy Taker.

I don't care for the Trap Door because I am to lazy to cock it on every shot.

I hunted hard with the Zero Effect for two plus years and never had a problem with it even in harsh conditions and terrain.

This year I hunted with the Trophy Taker both in the mountains and the midwest hunting whitetails. It has also turned out to be an excellent rest. I didn't like the TT arrow holding system so I scraped it and after modifying an NAP holder attached it to my shelf. I also cut and sewed a leather "bra" on the prongs of the shakey hunter to silence the draw. Both work exceptionally well.

In my experience with the MZE and the TT if there such a thing as one having an advantage of one over the other it is minimal. Every now and then I would catch my pants with the capture arm of the MZE as I was walking. I know I could turn my bow the other way but I normally carry it with the sight and rest close to my leg. More to protect my sight's pins than anything else (also I realize the arm can be modified). I don't have that problem with the TT.
