I currently have a Ride Control cambered 151 board, but I'm thinking of upgrading to the Arbor Element RX now that I've gotten better and heard great things about this board with rocker. I'm 5'6" 142-145lb (though I'm hoping to get down to 137lbs again!). Which size should I get? And it looks like the bottom comes in white font on black background, or black font on white background. I want the latter, but it does not look like I can choose. Anyway to request what I want if I choose to order from Back Country?
