Just thought I would comment on this as it is abit interesting: Ron LeMaster is correct, since you are infact out of balance when you intiate a high performance turn.
From the crossover to about the first third of the turn, your CM is actually too far inside your base of support to be balance The basic physics principle here deals with turn shape, we dont in reality ski perfect half circle to half circle, intiation is slower, turn radius gets progessivly tighter, then lengthens agains at the end of the turn, yet we incline to antcipate what is coming...I know some will argue that you incline as the forces build, and this is true to a point, but not so much in the intiation where you have much more inclination and very little angulation. It is more true in the body of turn as you approach, hit and leave the fall line.
The term used is "toppling" and refers to your state when you intiate a turn with inclination. In any high end turn, whether you pivot or not, you begin by allowing your body to move inside, whether this move happens from the ankles or at the waist is a matter of perspective and is debated often (not that I have been following the waist steering thread closely, but from what I gather, that is what is being said....not an entirley new idea). Ron explains this better then I can in a few lines with no pictures, but look up his idea of "toppling" it is explained better there.
Hence the angulation is a way of increasing edge angle without further throwing your body inside. The idea that when we ski we should be in balance at all times is actually a myth. That is real life skiing.
