i'm personally a fan of dunlop over most anything else, however i haven't tried the newest michellins yet. it's a much stiffer carcass, psi will be 5-10 lower than your pirelli, definitely needs warmers, or two medium paced outlaps. and if you're thinking they're not good enough, are you running AMA lap times? because thats the same tire they were using and it worked out pretty well for them for awhile. not the best tire but absolutely capable. i've got two sets in my pile of reserves right now actually. also, the front will last damn near forever.
Shut up and ride.
