"The Rudder" or "Blind dating" could have something to do with balance in the begining. However, for more advanced riders this could also be the nature of the way they were taught (or not taught).
For me, this ties into the bumps on board thread. I was fortunate enough to be taught by an expert rider who also was an instructor. His technique was aggressive, fast, backcountry, and technical. After my 3rd day on the board, he took me to the bumps, and the rest of the first season was in the bumps and trees...no warm ups on groomers. I was in a lot of pain, cussed him often, and was very tired after each day; but, by the second year I had learned good form, balance, and proper strength.
Naturally, I ride like him. I do not have a rudder, but that does not make me a better rider than my peers in the backcountry/aggressive style. In fact, I've been out with Rudders who could really lay it down at the resort and the backcountry.
