That's wonderful news, Kojak. After 5000km, my rear 700x32 supreme is starting to show some wear (still no flats, though) and I was thinking of replacing it before the winter. Oh, and while cleaning the tire, I found a shard of glass that had been wedged in there. I had seen this spot on my tire for quite some time and thought it was just a cut, but on closer inspection discovered it was a small shard of glass and pulled it out. It was in there for at least 1000km. Those tires are tough!
As for the 700x28s, if Schwalbe can make them, I'll buy as many as I can.
