The thing with the cables is they are not moving so much as the string to make noise. The most movement is in a vertical fashion, not cutting in the wind like a string with a horizontal slash. What do they move at the most, 1 inch horizontally?
Then again I've tried the cable silencer products before and couldn't tell much difference with or without them on. On my assault there are none but I also don't have to have whiskers on the strings either with the dual stoppers.
If it makes you happy run them, heck run 8 sets, I just can't see the need for them to be there.
