why do you call yourself kiwi ?
when i read kiwi on board , i thought there was a problem
also about 100 kg dry here
120+ liters is supposed to handle about 5.0 - 9.0
130
140
150
160 liters handles about 7.0 - 11.0 depending on width
for my 8.5 i use a 46 cm weed fin and love the combo - on a 160 floater
tried an 11.0 which was oversized for the board, but flew
since i liked the high speed in light wind, my next step is 10.0 race sail and then SB formula board :-)
anything under 100 liters is overkill for our weight - unless you are PRO
so , as someone said 105 - 200+
