Just put PR4s on a couple thousand miles ago. Used mostly to commute, in the rain they give no unpleasant surprises. Had to get the GT for the rear as the regular only comes in the 180 size. Don't know if the slight extra stiffness helps or hurts as I haven't had a chance to tour or to flog it in the mountains yet, but the bike feels fairly sure-footed pushing it around curvy ramps and evading car-commuting texters.
