From my view, judging by the turn where you're passing in front of the camera, your fore/aft balance doesn't seem to be too bad - your hips seem to be atop of your feet through the upper portion of the turn. But I might be wrong, you as the skier probably have a better perspective on this.
What seems more problematic to me is that you're initiating your turns with your (new) stance leg. One can see a consistent up move and A framing. You do seem to be patient and balanced after that, so you still get a relatively smooth turn, but it seems to me you could still see quite an improvement by keeping that free foot flexing and tipping through the last 1/3rd of the turn and making sure you're not extending in transition. Practicing 1FRs/Super Phantoms with a focus on not extending the old free foot might be helpful there. One other thing that I'm not sure about is whether your CA is kept long enough - you might play with that and see if it gets you some more energy out of the turn.
Edit: on a semi-related note, if you use Chrome and enable the HTML5 beta in YouTube (http://www.youtube.com/html5
) the video slider now moves the video frame-by-frame. Awesome for MA.
