When I had 650's I rode Gator Skins. Texas roads are just horrible for debris, I just hate changing a flat on a country road with no shoulder, big ol' trucks driving by and a drop off to a ditch. In a year of riding Gator Skins I only had one flat on the road and it was because I hit a HUGE rock dead on.

NOw they definitely aren't racing tires, but I loved those things.
