|I want to be sure I understand...you are saying that performing a weighted release (just one step away from one footed carving) is totally easy for beginners?
Yes! As an example, think of a simple sideslip. Stand across the hill in balance, naturally, with a little more weight on the downhill ski (also natural). Slowly tip your skis (I agree with Harald's focus here on the downhill ski, tipping toward its little toe edge) until they release, and sideslip as fast as you can, keeping your balance still somewhat more on the downhill ski. Re-engage the edges and come to a balanced stop.
If a skier can do this, or even approximate it, it is an easy next step to guide the tips down the hill to initiate the turn, from the sideslip. It is also easy to release the edges in the exact same way from a moving traverse, or from the end of a previous turn.
Note that I've described something very similar to that "release" exercise Harald demonstrates on Expert 2,
except without the pole plant. With both skis on the snow, and an open (not necessarily wide) stance, you can use your legs as much as needed to guide the tips into the turn as quickly as desired. There is absolutely no "pushoff" (which would require setting the edge(s) and slowing or stopping the sideslip), no "tail pushing," and no upper body rotation or blocking pole plant needed (both of which tend to twist the skis into a skid).
Note that this turn, by definition, begins with somewhat more pressure on the downhill ski. As the turn unfolds, and gravity and centrifugal force combine to pull the skier toward the outside of the turn, the pressure will move toward the outside ski naturally, so there is a "weight transfer" but it is entirely passive. The turn will finish with the weight still somewhat greater on the downhill ski, ready to begin the next turn!
Practice will increase both skill and confidence. Speed will increase. At high speed, the passive weight transfer may happen very rapidly, almost immediately after the turn starts. It can be hard to distinguish this passive weight transfer from an active weight transfer prior to the initiation, because the difference in timing may be only microseconds. But it is still significant. The active transfer disturbs the motion of the center of mass, causing a discontinuity, a "glitch" in the transition. The difference is much more marked at low speeds, so understanding is critical, lest we teach the wrong movements! We must be patient and allow the weight transfer to take time at low speeds.
As the beginning skier actively guides his tips down the hill following the edge release, it is likely that both legs won't rotate at exactly the same rate, and a small wedge may result. This is ver
ydifferent than a "stem," which describes pushing the uphill tail up and away from the downhill ski, into a skid, generally before the downhill ski releases.
