RE: zero effect
I chose a Muzzy ZE for my Diamond Liberty and had it installed by the bow shop. Well, it ruined my cock vanes right away and the bow was noisey (a Liberty?) Brought it back a couple of times. Still a problem.
Well I am not a bow smith and I am new to high tech archery but I am sort of mechanically inclined so I re-read Gregs previous post regarding this rest, watched the DVD that comes with the rest and... duh......it works perfectly now.
I know, I know...find a new bow shop.
I like the rest a lot.
