WAS--remember that a narrow(er) stance is the result of improving balance and good technique. The WORST way to achieve a narrow stance is to pull your feet together.
Remember that the same g-forces that pull YOU toward the outside of the turn also pull your inside SKI toward your outside ski. Far from pulling your skis together, good skiing requires RESISTING this force--actually pulling them APART!
This is what Dchan is referring to when he describes "active steering of the inside ski." If you don't pull the inside tip into the turn--away from the outside ski, the inside ski will interfere with the outside ski's ability to carve. Your only choices then are to go straight, or to push your outside tail OUT. Try this--hold your hands in front of you with the fingertips of your right hand touching the fingertips of your left hand. Now try to turn your right hand to the left (or vice-versa). It should be pretty obvious that, until you first pull your LEFT fingertips to the left, out of the way of the right fingers, you cannot move the right fingers left. The same goes for your toes--and your ski tips!
Of course, as soon as you DO pull the inside tip into the turn, the outside ski can turn as well, in a sense "chasing" the inside ski. So the stance can remain fairly narrow, if you choose. This is the sensation I feel in almost every turn--that I'm pulling my inside ski away from the outside ski, but that my outside ski keeps chasing it--all the way through the turn.
It sounds like you are experimenting with an open mind--keep it up! Try anything, but don't assume that something must be "right" just because Harb (or anyone else, including me) says it is! If something doesn't work--it may well not be your fault....
