I was wondering if anybody puts silencers or any Sims Dampening devices on your Switchbacks or Outbacks? When I bought mine they told me that I wouldn't need any of that stuff because mathews has the cable bumper things (thats the technical term incase you didn't know) and the harmonic dampeners.
My Switchback seems like there is a little bit of twang there that could be prevented with some string silencers.

I think I need to shoot my old bow again so I appreciate the switchback as much as when I got it!
