One of the most beautiful and extrem sessions I've ever had. "The Fog Phenomenon" at Walchensee. You only got this gnarly winds within very strong fog, as soon as you got spit out, there is basically nothing. Beautiful to watch, pretty hard to sail in there as you can't go full speed within the fog. That would be kind of a suicide commando. Good for the 10 sec. but too risky to go full on the 500. 

Stuff is working incredible. Not even used my speed foil, was using the NP F4 70cm frontwing and the normal backwing. So stable, feels unreal.
