Experience with Rene Herse 38's.
7 years ago I rode the Louploup Pass tires 2600 miles, and had the same number of flats as my partner, who was riding on Gatorskins. Of course, the tires were pretty worn by the end of the ride. I rode 75 - 100 miles a week, and switched to the EL version (because my lbs had them in stock) a couple of months ago, and have gone through a fair amount of glass with no punctures.
