It's not that difficult. Get the right size board and you'll be fine. If you're a big guy with a small board it won't be comfortable. But get a large board and it'll be fine.
When on my wife's board which is 6" shorter and 4" narrower i really have to pay attention. When i'm on my board i can relax, look around, move around on the board comfortably.
