Some Bowtech-manufactured bows do indeed require the cables to be crossed above, as does the Black Ice. I've installed MZE's on my '06 Tribute, '06 Ally and now my '07 Ally and yes, the cables do indeed touch slightly but I haven't had a bit of problems out of them. In preparation for my upcoming elk hunt in August, I've been shooting in the neighborhood of 50-100 shots every day for the past couple months on my brand new Ally, and it looks no worse for the wear than it did the day I got it.
