I'm still racking up the miles on them, but I've been riding a pair of Kenda Kriteriums for a couple months now. 199grams and they roll pretty fast. The best part is that they seem to be quite a bit more durable than my panaracer stradius pro. The panaracers are a bit lighter and I perceive a slightly faster ride. But not enough to worry about them going flat on a ride.

The Kenda's are marketing some iron cloak technology that helps resist flats. Seems to work well. So far I'm impressed, but I have only 500-600 miles on them so far.
