My boyfriend weighs about 210 and the board he's ridden most in the last few years is a fully cambered 159. Please note my location. He has bigger boards (up to a 172), and the split I got him is a hybrid rocker 166 because he's talked about getting a longer one when he got a split, but he's been riding that cambered deck just fine, even in fairly deep coastal pow, where you can really auger in if you sink it.
