Interesting change, your back foot is still right on top of the mast, which is too far back. When you move the mast you have to change your feet. Because, the balance point changes on the board. Try moving your back foot around forward and back to see how it changes the balance. Your back foot should be over the foil not the mast. I see you like angle your back leg down to maintain control, which is not something I have seen others do, so try moving your back foot instead.
