Exactly YM. This whole conversation is becoming ridiculous and a bunch of malarky. The only reason we are here is because certain people are stuck on the idea that counter-balancing is somehow contrary to moving the CoM down the mountain. So they are trying to come up some kind of demonizing perception of high-C engagement. Its their loss.
In their view, they use the slogan "GO" skiing to refer to moving the CoM down the mountain, and counter balancing high-c would be somehow detrimental to that. There can be a place to talk this way with someone who is extremely defensive, so I understand how this thinking came to be. But if it has led them to demonize counter balancing, then they are missing out on balanced and refined skiing. Arcing, brush carving, its all the the same. One way produces faster skiing then the other, but both require counter balancing to engage the outside ski and obtain reactionary forces that power turning of the ski. Sending the CoM down the mountain without counter balancing, at the expense of balance and engagement is an outcome that is exactly the opposite of "GO" in my opinion. It will result in very defensive tactics in the lower half of the turn, which include both brush, skidding, braking, turning far out of the fall line, even turning up hill if need be...its all the same..its all defensive.
The idea of demonizing brushing is also entirely ludicrous. Every one of these same people would be demonizing arc to arc skiing if we were talking about that now, so the truth is these same people know how to brush the low-C part of their turns, and they rely on it for turn shaping and speed control. Is that defensive? Is that swimming up stream or downstream? Is that "GO"? They are all doing it already. What they don't want to grasp, and I will claim with confidence that they simply do not understand because they don't own it....is that high-C engagement and brushing, brings the refinement we are talking about YM. And it is exactly this that can result in less braking in low-C and over all a much more "GO" set of linked turns. it allows a skier to let the CoM go more freely starting just after the apex of the turn and through the release phase, which is exactly WHEN you want to let the CoM go! Later on as the edge change happens, its more advantageous to counter balance and engage the skis.
People that have gotten off the reservation in terms of sailing the CoM into the turn down the mountain during the first 1/3 of the turn are dead wrong. That method may seem like more "GO" for that phase of the turn, but it results over all in much less "GO" skiing. It results in lack of balance, lack of engagement during high-C and lots of making up for it in low-C.
