i also think your fine with the board size, but i gotta ask whats your binding set up look like? are your toes straight? is the binding not centered on the board properly? are the highbacks setup so you lean forward in the binding? If any of this is so make some adjustments, you can change the angles on the binding so your feet point outwards, thatll give you a little more space, and should be a little more comfy. Tinker with it. It took me 2 days on the hill messing with them after every other run to figure out exactly how i wanted my bindings set up. Make sure your comfortable, riding will be a lot funner!
It comes and it goes. Get it while it Lasts.
