Lets see him do that when its windy hahaaha. kinda cool but not real pratical for most days, you could just slide your fins around and spin the board upwind then just ride back switch, and still loose no ground.
Isn't this basically a back loop. I seen guys doing this with single and double back loops. Kevin Langeree does it here in Cape Town in big shorebreak, but he gets quite a bit of air to get him over the shorebreak and throws in a loop or two, but the nose of the board goes into the eye of the wind and is therefore a tack, not a gybe. Very stylish.
