I got to ride the new version of the X Model last weekend. It's been a few years since I rode the original version, so the only difference that I could tell was in the appearance, but I'm sure Mark has done more than this to improve the ride. In my review of the TS 202 I stated that if I was going on a trip and didn't know what the conditions would be and I could only take one of my boards it would be the TS. That is still true, because I don't own the X Model. The X has the same overall shape as the TS and approximately the same waist (22 cm-ish), but is stiffer in the tip and tail. I would feel comfortable taking this board in the trees, powder, bumps or groomers. Mark calls it "Any Mountain" rather than "All Mountain" which is accurate. There is enough tail rise to ride switch and enough nose rise to take it through the deep. It's surprisingly quick edge to edge and will rail like any Thirst board I've ridden. It was really fun and I wish that I never rode it.
