Surfing and Motocross Help Pleaseee!!!?????? Please answer as soon as possibleeee!!!!!! Thankss soo muchhhhh!!?

Im 14 and im riding a 5'11" but i think you should try something like a 5'11" or 6'0" seeing you wakeboard and snowboard u should have a bit or experiance with the water but if u r looking for a longboard the size dont really matter. Any questions my email is Matt_surf@hotmail.com
