Both.
I have Road Attacks on the Mighty Scura, Classic Attacks on the Monza, and Sport Attacks on the MZed out in SoCal. No idea on how long the Sport Attacks will last.. don't care really.. but they are the best tires I've ever used in the twisties.
The Kid has Classic Attacks on his 1100 Spot, and after a rainy day in the Carolinas said, "These are the bestest tires I've ever had."
Uhh, I'm a fan.
