I've ridden Pirelli Supercorsa, Rosso III and Angel GT. I've managed to push the front once with the Angels, but that was on a dirty, off camber up hill turn where I started trail braking before getting off the throttle, so.. oops. While the Rosso and Supercorsa inspire more confidence, the Angel GT hooks up very good and gets much better mileage. I got 3k out of the supercorsa, 4k our of the rear on a Rosso III and have 5500 on the Angels now, front looks basically new and the rear probably has another 1 - 2 k in it thought it suffered dearly in the Nevada heat on my July roadtrip and has more of a flat spot then I expected given my experience with my previous set (on the old bike, 7k and the rear is barely showing wear).
