My vote is Bridgestone Potenza RE-11 if you are using them for street and track.
The RE-11 are very quiet, relatively comfortable (for an extreme performance tire) and would be better in the wet than its competition. The AD-08 would likely be a slightly better dry track tire (based on various reports) but the RE-11 would be almost as good on a dry track but better in the wet and better for comfort. I just put the RE-11s on the car and they are really a great tire all around without sacrificing much anywhere. They are one of the best dual role tires out there IMO for people that run them daily but also want to go to the track once or twice a month.
