Gatorskins would be my recommendation I currently use them on my commuter and love them. I ride through a lot of nasty roads that are pocked with potholes and glass and other crapola and don't have issues with flats. My new touring bike is going to be running Gatorskins or Gatorhardshells as well. The only bike in my fleet that won't be rocking gatorskins is the Cilo my vintage road bikin' baby and I guess the DT till i sell it because no Gators in 26x1.5 or 1.75 but I haven't had issues with the Contis that came with it.
