I do like it so far. Not pushed it yet as only just scrubbed in. We (wife and I) had a little slide on some of that shiny repair stuff they fill cracks with after about 225 miles, enough to make the wife slap me
. It was dark and raining heavily with some surface water (B711 west of the reservoir) hence I didn't see it. As Lance says when it loses grip it does so gradually and regains grip the same way. Did 325 miles and all seems well. I was well happy with the PR3s wet or dry so we shall see with a few more miles. As for heat, to the touch the PR4 front felt similar to the PR3 rear, but that's very subjective.
