Some find success with the tape option, I sure hope you do. Probably best to bring a tube as a back-up plan. I wish there were tubeless real knobby tires in the narrow size the XT requires. I can get by with a dual sport type Shinko 700 rear tire, but not for critical traction requirements needed for the front. Lack of critical grip on rocks or roots means things go sideways real fast. Let alone the grip a real knobby front tire offers in muddy ruts and water-filled Jeep wallows on the trail.
