I love my Gatorskins, they ride great and never give me any problems... Except after about 2k miles I'll get a flat, usually some slow leak that I don't find until the next day. Its all downhill from there, the tires seem to actively seek out little glass shards, wires, and bits of metal. For me that means a new pair of tires every 2 months. Sorry little bit of a rant, 3 flats on my last 3 commutes.
