thanks for bloody fast answer...not sure the foil is right for me...use the smallest mfc shim to get a little more lift...but when the mast is more then 50% over the water the board becomes unstable...before its ok ok...but no really long flights possible...use the 91 cm wide rrd h1 with 150 liter...a 6.7 sail and try to fligh in around 10-15 knots...
Im 98kg and 187cm...

may lots of more time needed...had to much strong gusts last time trying...
thanks in advance
