Sorry about your luck with the tires. I am commuting with a Forte Kevlar Pro 700x23 on my front wheel that I bought as a replacement for a blown Bontrager RaceLite Hardcase. No problems so far, and it seems nice and grippy for general usage. I have about 400 miles on it so far with no flats. Admittedly it is a front tire, so it will see less wear and tear.
