RE: gotta get a new rest....
I'd like to know that too, Rich... as I communicate pretty regularly with Muzzy's tech support department and haven't heard of too many problems yet. Mark at Muzzyeven confirmed they installed a MZE on the Diamond Black Ice successfully, and that bow has very limited slide travel. They did have to cross the cables above the guard I believe; I haven't put one on mine yet, but will.
Just to clarify too Rich... not accusing you of being wrong here -- just looking for some specific info. Thanks.
I have heard of some challenges with the Guardian... I'll be attempting to set one up on that bow when I getback in town in a couple weeks.
