DH put a pair of Gatorskins on my bike in October because I was flatting all the time. I refused to ride by myself because I flatted so much. The area around us has a lot of construction debris and trash. At the risk of jinxing myself I have not flatted on the road since getting the Gatorskins. I have had one or two slow leaks that went flat overnight.

I recently replaced the front tire because the sidewall had a bulge. They probably aren't the fastest tires, but then again they are faster than zero mph to change a flat. Honestly my old tires were nothing special (just factory on a entry level bike) so I couldn't tell a change.

The guys at the LBS back in College Station swore by Armadillos for training. The girls (I love it here- women in the shop) at the LBS in Austin said many of them use the Gatorskins for training.
