Have a look at this video we made last weekend at Folsom Lake, California.
Rider (me) is 220lbs, wind is 8-10mph, board is Litewave Wing-161, kite is 17m V-Sonic.
Going upwind, having fun... This board/kite combo works soooooo well for light wind. See for yourself. Video is real. No fake. My wife took it.

The way this board flexes it feels like a snowboard in powder.
