You've yet to mention your feet. Being brutally honest here, but until you start skiing from and feeling what your feet are doing, you'll be stuck in a long, hard, rut... Form FOLLOWS function. Function/actions start at the feet. I'd love to have you do some small one ski railroad track turns starting from and focused on tipping your foot. It would clarify the idea of what the feet do in short order. The interesting thing is a disciplined upper body with some functional core tension make it easier, but only your foot will turn the ski.
I am not sure thought I was but my feet seem to be in the right position to me. My inside ski is initiating the turn its not behind the other ski. So please explain.
