I bought the Michelin Road Pilot 4s and scuffed them in today at a moderate pace in the canyons. Even at a conservative pace I felt they were much easier to turn in than the 7K mile old stock Metzlers.
I also got a great price on the pair, installed of around $420. I do need to go back there to get right angle valve stems, as they didn't have the right size stems handy.
