I could not agree more. Poly is much too harsh for the street. I've had poly control arm bushings in my Suburban for 5-6 years now and I'm totally over it. I got some junkyard control arms, going to restore them with new rubber bushings and install them. Poly will rattle anything and everything, even going over a pebble is noticeable.
