I'm a big fan of Specialized Flak Jackets(All Condition,Infinity,Nimbus) and Vittoria Randonneurs. No flats with either. I'm on the fence for Conti Town & Countrys. Five flats(2 front,3rear),but after the 3rd rear flat I found 6 other pieces of debris in the tire that didn't get through. Still,zero flats with the other tires under the same conditions.
