I am currently using Specialized tubes and Bontrager Hardcase Racelite 700X23 tires. I normally use SpinSkins, but could not find any at the LBS when I changed tires last time. The Hardcase have a built in kevlar belt anyway. I have used the Specialized tubes for almost ten years now.

I tried Forte tubes a year ago. Within a week every tube failed at the stem to tube bond.

Using the SpinSkins I might have had three flats in the last five plus years caused from road debris. They involved large nails/screws, and a piece of metal roof flashing that took out the tire. I have pulled shards of glass and staples out of the tire case without the tube flatting.
