I've got Michelin Dynamic Classics on one of my bikes in 700x20 size. They ride quite nicely. They've got a conventional rubber tread, so no fancy sticky compound to pick up debris and cause punctures - so I think they're good for commuting. Rolling resistance is good. Tan colour is a good classic tan colour (important for us, in my opinion). I've done about 2-3000 miles on mine and they're maybe 1/2 through their life, but my roads are pretty terrible and prematurely chop all my tyres up and I'll have to replace them before they're done. I'm going to be getting another set for the other bike.
