Move the bindings back to neutral. I have actually head that moving them one hole back may actually help. Does not make a lot of sense but might be interesting. I just spent a week with a coach (fourth year now) and we spent lots of time on just that problem. There are lots of things that you can try. 1. Do not turn with a stiff front leg. 2. Keep the weight on the balls of your feet. 3. Shift your weight forward by moving your hips forward vs. crouching and using your shoulders to 'get over the front'. 4. Keep your head up - don't start the turn with your head and shoulders. 5. Don't release your outside hand too soon. 5. Reach forward and in and up a bit so your ski can turn by itself under the rope. 6. Don't rush your turn - avoid turning into slack (definition of slack varies) - let the ski finish 7. Increase your knee bend as you approach the first wake.
Video is a good idea.
Try Andy Mapple's second Ski Paradise video. It has good instruction based on analyzing amatures at slower speeds and longer ropes instead of how to ski 39 off.
The biggest mistake I make is turning to frequently - making 8-9 turns in the length of a normal slalom course.

Spend as much time as you can with a coach.
Relax and have fun.
