they used to be the only tires i put on my bikes until about a year ago. was always very satisfied with the flat protection, with the biggest problems being small sharp objects as stated earlier in the thread. i would normally experience 1 flat per 1500 miles, which is totally acceptable to me.

unfortunately (AFAIK) the largest gatorskin you can buy in 700 is a 28c. I moved over to the vittoria randonneur double shield 700x40c for the past year and have had zero flats. absolutely love the tire, though it's major downfall is weight.

just switched over to a 700x35c Panaracer Pasela TG about a week ago and love the feel of this tire. not as light as the gatorskins, but possibly a better ride than both the GS and the Vittoria. time will tell re: flat protection
