I have the Outback, and had a LX, and the harmonic dampers and string suppressors work great. I use the brass dampers. I took the stablizer off my Outback due to it just doesn't make a difference. This is the first bow of about 50 I've owned that doesn't need a stablizer. I told my wife one day that the string suppressors were just a gimic. I decided to pull the suppressors out of the arms. After 4 shots, I was putting them back. There was a small amount of hand shock without them. I put a set of Limb Savers on the bow but I really don't think they add anything. If I were to have a dry fire, they might be a "limb saver". I have a loop, kisser button and two small whiskers and I can't think of any other item that would help or make a difference. Don
