I ran these on the Tail of the Dragon this weekend, and NeverEnough is right:

Very nice as far as damping out vibration and road noise, but the sidewalls can have a sudden disconcerting flex in the really tight turns.
Still stuck tight, though.

They are a good bit stickier than the stock Conti's; I stayed right with an SRT w/the Conti's, and ran tighter in the lane with fewer traction brakes (I ran traction ctrl on, and his was off).
