I remember Laird Hamilton doing it in the 90s (80s?), but that was at Jaws and didn't have quite the magic that the above video had.
Love the way he can "pump" it, that'd be good exercise. But think I'd miss the lack of edge control, he's not exactly smacking the lip.
Foiling looks ungainly. I was more convinced by the SUP video that came out a little while ago but still there's so much pitching of the board in all the foil-board sports. Rider is always fighting for stable trim.
ya might be whinging about SUPs right now
but just wait till the masses are riding down a swell at you with something that slices, dices and juliennes
