Thanks for the reply's. Here is a picture of the stance I'm referring to. My stance is usually reversed of this with my front leg bent more.
The 44 is a bit extreme. I wanted something bigger than the stock 34 size and maybe went a little to far. But, on flat water I can definitely lift the upwind rail and ride the fin. Its interesting if nothing else. There definitely isn't enough board width to control that fin in anything other than flat water.
I position the mast base in the center. No real reason. I haven't played with different positions a whole lot. Crazy, I think your explanation of the downwind makes sense, but then my question would be how do you or do you change your stance to go upwind. Are the articles I've read about front foot vs. rear foot riding only pertaining to wave riding?
