The VFT bows have problems using the muzzy zero effect in its traditional configuration because they have very little movement of the cables on the cable slide. This is what actuates the Muzzy, so if it doesn't move enough it will be hard to get set up and the timing may be way off. Sometimes you can get them to work, I couldn't on mine. At least not in a mannor that I was comfortable with. I will just put it back on my darton is all.

Also on my bow I found it put a fair amount of stress on the cable guard, more that what I wanted. Mine even came loose once. Like I said though, they make another style that hooks to the buss cable instead. It should work better on the VFT style bows.
