If anyone else is looking for wakeboarding recommendations, there's this guy named Michael in Sai Kung who speaks great English and includes everything for a really reasonable price (even on the weekends when you would get gouged by companies in/around Hong Kong island). His contact is 9663 9666.

On the same note, I do NOT recommend "Wake Plus" or its affiliated company "Wakeboard.hk". Both have some of the absolute worst customer service I've experienced in a long time.
