I own a boat, water skis, and a tube. A friend that I do a lot of down hill (snow) skiing with wants to try wake boarding and is willing to buy a board. We both have size 10.5 and he ways about 170 and I am at about 185. I think he is about 1" shorter than me. He is a little more crazier than I am, though what suggestions do you guys have? We were taking a look at the Hyperlite Vapor 139cm board for about $239
