you mean UltraSonic ?
for me on a wide board - head downwind to plane earlier
some people pump, i only try three or four - no more
some people like Roger suggested i move the sail back
now my 10-oh is in the middle and 8.x all the way back !!
good luck and enjoy
i am so happy FreeFormula boards of 90+ cm width are coming back !!!
Excocet RS-7, Fanatic Falcon 152, and BIG FreeMoves too
