One is a naked outlaw, a trouble-making desert rat, a pioneer of the sport. The other is a hard-working and self-disciplined kid from Estonia who is blowing up trick-lining comps all over the world. Andy Lewis and Jaan Roose are undisputed masters of slacklining, pushing the limits of the sport with audacious tricks, risky feats and incredible acrobatics. Their approaches are worlds apart: One flips the bird at authority; the other flips 109 times on command. But what fuels them is the same — passion, creativity and courage.
