I've had one experience with Michelin Power Cup (B compound) tyres and whilst they do grip awesomely, they also wear out really fast. I rode a friends ZX12R at a track day and between the ride there, some 60 laps of the track and the ride home (about 450 miles total) the rear tyre was shot. Was fun but turned out to be a really expensive track day once ya added in the tyre.
