Bridgestones for the X-bikes are G704 and G709. They are a populare combination with the Wingers and at least one member (Jagular) besides me has them on an X-Bike. I can't tell you much about them personally because I only had about 50 miles on mine before I had an accident. Once my bike gets out of the shop I may be able to give better info.
