I really like what RicB and Arcmeister are saying. This is what I would want my student to feel and be doing. My own skiing is changing in this regard and I don't feel quite the same thing as what is decribed here anymore.
My stance width has increased over the past season as the type of rotary I am using to steer my skis has changed. I am using much more of a bulldozering motion that originates in the core instead of a fulcum motion that comes from the hips. My outside ski is running faster than my inside ski and the skis each leave very narrow individual tracks even when they are not producing RR track turns. This type of steering has just about eliminated any unecessary tip lead.
I feel myself skiing out of counter at the hips in the last third of the turn even though my torso is facing the new turn. I think this is because I am decreasing edge angle, keeping my hips over my feet and the outside ski is running faster than the inside ski.
There is a windup of sorts but instead of a quick edge change, I tighten my core and my skis tips start to seek the falline while they are still slightly on the uphill edges. As soon as the tip start seeking the falline I dorsiflex the new inside ankle more than the new outside ankle and roll smoothly and simultaneously through both boot cuffs onto the new edges. This slight dosiflexion of the new inside ankle allows my inside hip to move nicely forward into the power position starting right at the feet. This completely eliminates the kind of upper body motion that has us moving inside the turn to quickly at the top of the turn in order to gain a higher edge.
I can easily pick out my tracks as my turns are well finished and there is a flat spot where both skis hit neutral at the same time. The neutral spot in my tracks is much flatter than it use to be because the edge change is even more progressive and less abrupt. The edge change in my tracks use to look more like a carving snowboard but now mys skis progress off edges to flat and back onto edges over a longer steered track. The skis are tracking an arc into the new turn even as they go flat.
The whole thing I am feeling is two active feet with the ankles able to move in three dimensions all the time. That means active steering right through turn transition and neutral with no momentary shutdown of steering at edge change. I guess I don't feel much of any unwind anymore, everything just flows with constant activity always forward into the turn. I use to edge then guide. Now I never stop guiding or edging through transition. Both feet seem to be guide and ride all the time now. I guess that is why both skis leave their own narrow skidded track in short radius turns now.
I still teach edge then guide and that you have a ride and a guide foot. I think that simplifies learning for students. For a change, I don't think my teaching has caught up with my skiing yet this year.
