Firstly, board size is determined by weight, and shoe size. Height has little to do with it anymore.
Secondly, it is impossible to tell you what kind of board you should get without knowing what kind of riding you intend to use it for. You ride mostly groomers? Want to ride park? Hiking rooster comb?
I have my almost every day board (bataleon riot) and a pow board (Burton Jussi)
I ride Stevens pass at least once a week, usually 3 days a week. I hike when we have no fresh snow.
Rocker is ok around here, I really like cam-rock boards for our terrain/snow. C2 Power Banana rides pretty well.
let's not talk about it
