I have shot muzzy zero effect drop away rests on every bow that I've owned and loved em,the FRED BEAR TRUTH BOW,is the only bow that I have owned that it wont work on,mark land at muzzy will tell you it will work on the truth,it won't,Any PRO ARCHERY SHOP,will tell you the same thing,it will not work the draw cycle is to short,or power stroke.the truth is an awesome bow but unfortionatly the muzzy will not perform correctly on the bow,spend your money on something that will work on it, Schupbachs in jackson MI. or Long Range Archery in Twin Lake MI. will both tell you the same thing..........Ted
