I went with the Pirelli Night Dragons when I replaced the front and back tires on my bike early this spring, and I have been very happy with the ride and grip they give me. Bike feels more planted and grip has been exceptional in many different riding situations. I don't know how long they will last, but i have about 5k miles on them and they are going strong. I would say I am only about a 1/3 through the back tire, and the front tire still looks new. I waffled between the Metzler tires and the Night Dragons, but my mechanic broke the stalemate by recommending the Pirellis. I have not regretted the choice.
