I use the Conti GP4000s, which I've found to be about as flat resistant as Gatorskins. First flat was a front pinch flat, on the race bike, after hitting an unexpected asphalt edge at a manhole cover. I had tried slightly lower pressure that day, and I think that contributed. Second was an explosive blowout, with the tire bead popping off, rear on race bike. Second time with that rim, and I believe it was flawed, but is now toast anyway. Yesterday was a piece of metal, to the side quite a bit, that I'm pretty sure would have gone through anything. That was on the Gunnar steel road bike that I now use for commutes and some base rides. I want tires that perform well even when I'm commuting: will just have to work on my karma.
