I need to share my experience with the ContiRoadAttack 2 tires. They are hands down the best tires I have ever used. They are quiet, are wearing wonderfuly, don't have "dual compounds" so there is no transition feel, but rather one compound that is heated differently between the sides and the center tread. These things grip like glue and they didn't even need to be scrubbed in.
For a hypersport tire, they are the best that I have found. Definitely worth a look if you are due for a replacement.
