I do 50% highway (no choice

) and the rest split between city and enthusiastic twisties.
Installed a rear Michelin Pilot Road 2 last year, after 6,000 miles it still looks like new (prolly still good for another 4-6k), the grip is good once warm, and they have a great "sticky" feel.
I guess I rave about them enough, everyone around me is switching to them, and I just put a new one in front.
I would absolutely recomend them!
