Quicky search on the board finder:
Salomon Sight 166W 12/13 300 euro
Riding Style: Freeride, Freestyle
Men's / Uni Snowboard
Right length for your height, gender and riding style: Board Length 166 cm
fits your weight (86.14 kg)
riding level: Beginner, Advanced
However i agree its hard to find a board if ur a larger heavier guy
Checked Ebay.de for u and found this:
Burton Freestyle Snowboard 164cm with Flow Binders, 4 yrs old, 180 euro, not bad for board and binders i guess. Its just a suggestion tho, i like shopping for great online deals.
