aalvarez04 has the Dunlops on his NB and he doesn't like them much. I've heard good things about the s.drives.
I just bought a set of DD tires for mine. I gave these Continentals a try. They had really good reviews.
I like them a lot so far, they have great traction. They do not have a stiff sidewall so the ride is smooth and quiet, however steering response isn't the best.
