I know I'm two generations behind, but in my opinion, the Sportec M1s were the best value in a performance tire for sport bikes. They wore well, lasting 6k miles on the street with four hard track days early in their life.
They came up to temp within a lap at the track, and when they got pushed too far (too many laps too fast in the heat of the day) they slid predictably, and came back with just a short cool down.
I took my CCS licensing clinic on a Speed Four with M1s on it. The class final was a race. I won it going away, ahead of race prep'd bikes on slicks with 30 more horsepower, mostly because I was completely comfortable with the bike and its traction and stability.
I have to believe that the M5s would be as good or better.
