I switched from supercorsa sc2's to the michelin evo slick last year. The grip on the michelin was better as was the life, so i'll probably stick with them going forward. Not an apples to apples comparison between a slick and a street tire though, even though they share the same compound frequentlyI love the supercorsa's though. And I don't put many miles on the Tuono, can probably get 2 seasons out of a set. So don't mind paying the price. If Dunlop made a Q3+ in a 200 rear I would probably go to those. Almost tried the Q4s but not a dual compound tire and will surely wear faster then the SP's.
Have you tried the michelin's?
