Michelin Country Dry 2.15's are pretty good. I took mine off to tackle the serious bad weather for winter (DMR Redshifts are AWESOME in wintry conditions!), but 9+ months out of the year, they rock! Roll easily, slip/skid rarely, I've had ONE flat in six months of use (picked up a piece of shrapnel riding on a street adjacent to a construction area). As soon as I'm sure the nastiness is done falling out the sky, they're going back on.
I'm looking forward to seeing how they work with the new wheelset -- the Mich's are lighter than the DMR's, and my new wheels are feathery compared to the old!
