Truckman: Without more info I really can't give you a good assessment, but here are my thoughts based on what you've said. First, severe bending at the waist typically moves the hips back, therefore weight moves back and turning becomes a heel push or possibly a rotary push-off, ie-Bob Barnes discussion of the A-Frame in the Hyperchange Cafe,(Link).
Next you said that your left leg was much weaker then your right. This leads me to have you consider skiing as a Three-Tracker-ie one ski on the strong leg and two hand held outriggers,(a Canadian Crutch with a small ski tip attached). We use this adaptive skiing method for those individuals that may be post-polio, amputees, or others who have one leg, which is significantly weaker than the other.
Finally, may I suggest that you stop in at the adaptive center at Winterpark Resort. They have the foremost adaptive and probably the oldest program in the nation. They can do a complete dry-land and skiing evaluation. Once completed they can suggest how you might proceed to improve your skiing and make it easier, while having more fun. Good Luck.
