Bump. Gonna order tires in the next week so I wanted as many ideas as I can get. I'd love to get the Gatorskin Ultra with extra flat protection but apparently they are backordered. Was thinking about regular gatorskins, Carletta seemed to like them AND she is in Philly and I will be again soon too. I like the fact that the gatorskins aren't uber heavy like some of the others I've been contemplating. These ARE for a commuter bike though so I'm not basing my decision on weight.
