I'm running Michelin CiTY's. I've got the 35's... I don't have experience with the 28's, but I can't imagine too much difference. So far, so good. I've had them for maybe 6 months with no flats yet. Overall, I'm pretty happy with them.

Occasionally on nice wide empty side streets, I like to slalom a bit. Lots o' fun and they seem to handle well. They did seem a bit "stiff" at first, but once I slalomed around a bit they handle much better now.

Also, it has a reflective sidewall. This was something I didn't think super important until I took a picture, with flash, of my bike. Man, are those things bright!
