I tore my rotator a couple of years ago and could no longer shoot my mathews outback, so I went shopping. I got a bowtech Liberty with the Freedom Cams. Totally AWESOME. I can still pull 70 lbs but it feels like I'm only pulling55 or so. I was and still am amazed. My shoulder hasn't heeled and still hurts all of the time but I can still shoot my bow pain free. I cranked it down once and my wife shot it pulling 53 lbs and she struggles to shoot 45 on her own bow. I'd definitely give one a try.
