I've got one on my Captain, my Admiral, my IceMan, and my Carnivore 31. Had one on my 82nd Airborne but sold it along with the bow. I've got a Muzzy Zero Effect on my Allegiance and a Hostage Pro onthe Liberty.
Yeah, I'd say they work pretty well on the binary cam bows.
I may sell them all off though and replace them all with our Octane Tripwire rests.
