hey Paul, like Terry said, for 12th, I'm doing a group buy on tires at the moment, PM me. For TC, Sweep now has a QTS32BK which is a tire for the black carpet. This is also the spec tire you will get at the WCICS races, reported to work very well, and not needing nearly as much gluing. Tires tend to last a bit longer on the black carpet as well, both foam and rubber.
