Ive never had a pad that was silent on a grind, apart from when my yellows went really crap. Then they just swooshed. Surely unless you have a six inch thick steel booster, then theres still gunna be vibrations, ie. noise.
My grind, which i havent redone in a good 3 months, is almost smooth, yet i still get amazing lock with koxx reds. Why not try some koxx pads on a koxx rim JT, sounds logical?
