Just curious where you are orignally from. Not that it matters. Also how old are you?
At that height and size boots I'm assuming you're gonna be growing more in the next year or so. I personally am not familiar with the board type but you're still gonna be learning this season. If you're set on park riding then look for that twin tip and get the 147 and start from there. I don't think it'll be too small for someone your height and weight.
Who knows how you might want the board to feel as you progress. You might want a totally different setup for next season. You can always sell this board and use the $$ towards what you want.
