Yeah, for sure Mariusz is the only WSM winner ever to be so compact. Maybe Yuko Ahola (sp?) close, but not quite as in-shape.
The most impressive I ever saw Mariusz was two years ago in China, carrying that ding wotsit, a bell of some sort. 350 it weighs, he was smiling as he carried it back and forth, clutched to his chest.
Stunning.
