I have a lot more miles on the Ravens so I thought I'd give an update.
I love these tires. Haven't ridden them in the rain, yet, but they're the bees knees on dry pavement.
I don't ride stupid fast on the street but I get after it pretty good at times. No chicken strips on the front or back, but keep in mind these have a flatter profile than, for example, M3's and Diablos. Haven't had a slip, yet, and I'm still amazed at how nice these tires allow the bike to turn in.
Today, I noticed that some of the rubber flash between the sipes in the center of the tire is still intact and sticking out past the tire. lol. That's durability for you. Can't figure out how a tire can stick so good and still last so long.
