Hankook RS3s hands down. The noise level is my main complaint but its not terrible. The weakness of this tire is when it drop below 50 degrees for any amount of time, these tires are terrible. If it rains and the temps are below 50 degrees...they are dangerous.
If you need some cold, wet weather grip, I've had really good luck with the Dunlop Direzza's.
