yes i would have had a traditional wave session on my 10m c4 in 16-20 knots.
but that was not what I was after. I felt like trying to tame a wild animal!
PS i'm keen to see any footage you have of light wind speed 3 down the line wave riding. In my cross on location the only down the line action i get on the speed is when i loop it. overwise it looses line tension and starts flapping its way down to the water.
You cannot have down the line wave riding in Cross on winds unless your wave is breaking at a strange angle. You need the wind to be pretty much 90° to the waves direction of travel.
