I have run Mich Pro Race, Veloflex Pave, and Gommitalia Calypso with latex tubes. I typically rotate the tires every 500 miles or so and have gotten on the order of 4,000 miles from each of the above tires with no flats. I'm currently giving a pair of Vittoria Open Corsa Evo CXs at try. I think at the upper end, they are all very good. For price, the Gommitalia Calypsos are hard to beat. You can also find good prices on the Veloflex. I'd buy either again in a heartbeat!
