A couple points...
- Initially you don't need your CoM that far inside. the inside movement of the CoM can be very gradual and progressive. Simply shortening the inside leg, which you need to do anyway, can be all it takes and allows the creation of inclination to more closely match in balance the progressive establishment of Mr C.
- momentum is still there and you don't balance against momentum! What does this mean? It means you can be perfectly in balance with Mr G and no Mr C present due to ended centripetal forces, while still allowing momentum to carry your CoM across to a certain degree. Momentum is still there and still trying to carry your CoM that way if you allow it. It does not require you to go out of balance to do so at all! Its just that your balance during those moments is based on Mr G because Mr C is not established yet. For the most part, this momentum sometimes has to be constrained a bit actually in order to avoid falling out of balance down the hill, developing inclination of the CoM prematurely. Depends on how active you are with your lower body tipping.
- The trick is to allow either #1 or #2 above to happen as secondary to the feet tipping. In other words, make proactive foot movements with the legs and feet so that the Mr C will be generated at the same rate that inclination develops.
- It is definitely in some ways technically easier to just allow yourself to fall into the turn, however loss of balance means late edge engagement and pressure development. As you very rightly pointed out earlier, we want to ski into pressure rather then push on our skis to get it. But going out of balance initially works against the establishment of that skied-into pressure. This is part of the reason why so many out of balance skiers are pushing and extending like crazy to try to make up for the fact that they have poor balance starting their turns and hence late pressure development and edge engagement that they could have gotten from skiing into it that way.
#3 + #4 Excellent and important points!
