I don't know what size snowboard to buy?

155, kinda in your situation only a ride kink 155

hmmmm maybe 158 depends do you like park then get the 155 if you like freeride better get 158

i would go with a 155. since you are looking to buy a WWW you do know that they are designed off cambered this season meaning instead of the board being cambered toward the snow its cambered up, like the Lib tech skate banana. so it sounds like you are going to be doing alot of rails and park stuff. so i would go with the 155, it is easier to menouver, spin, press, and do whatever you want with it. the smaller the board the easier it is to spin. but in the end i would choose the 155

158

usally they put a weight chart on the back of the board aand this is the best way to tell, because all boards are made differently. if you fit in to both weight ranges determine wether you want a freestyle board in which you would op for the shorter board if you want more of a freeride board op for the longer one. But being that your looking at the WWW your most likely a freestyle person. http://www.k2snowboards.com/files/k2_snowboard_specs.pdf

I would go with the longer board...a 158 will give you more all mountain dominance..

I'd actually get a 161, but if they don't sell that board in that size, get the 158.

well, heres what i think i'd go for the 158 my brothers about 174 and same height and his board is a 157 and one of his other boards is a 158. hope i helped somewhat anyways, good luck and happy shredding! hollyy

a normal sized one becuz its easier to ride!=]
