Now we are talking!
But I think you aren't seeing the whole picture yet.
You can ski straight across the slope, now without any whatsoever rotation just tip your knees down the slope. Your skis will turn and the more you tip your knees the harder you will turn. If you turn hard you will also need to put your hip into the turn. This gives that you can after some practicing throw your knees, hips and body downwards the slope with your hips feeling like
they are pointing outwards the turn leading with your inside shoulder.
You should start by doing it gentler thou. However on gentle slopes I think radically tilted knees and even weight distribution between the skis works best for getting the hang of it.
Look at this picture series where I do some ugly a-framing by not tilting the inner knee enough.http://img149.imageshack.us/my.php?i...croppedbc7.jpg
There is no rotation involved, just arcing.
The second picture is what I'm talking about. I'm leaning downwards.
You can lean down the slope, no problem, just as long as the skis are gripping. The centripetal forces will keep you from falling over.
You can hang on to your turns as long as you want. You can even ski uphill and then tilt yourself the other way to turn down again if you have speed, sidecut radius and sharp edges enough.
