When trying to ride dark side do you move your feet more towards the heel side edge?

Yes and squat down lower. Try to sit down on the wave.

I assume that your normal stance is left foot forward? <BR> <BR>On the starboard wake you can ride heel side with your normal stance or you can ride switch – heels to the wake. <BR> <BR>In general and regardless of what wake you're riding, I find that moving your feet (heels or toes) closer the board edge that is in the wake helps beginners.
