Thanks Bob, as usual, you bring your precise clarity of explanation to the table.
Jamt, thanks for slugging through to help me get to that point of being able to understand this.
You have brought further clarity to the use of edging (and angulation to do so) to regain your balance. This is essentially re-aligning your BoS back into the Balance Axis. What lurks in my mind is that this feels like a re-balancing move instead of a way to ski well. You are correcting for something you didn't get quite right somewhere else or something unanticipated happened. Certainly a valuable skill to develop however. It certainly speaks to the high degree of interaction between these two moves (inclination and angulation). But the neat thing here is really beginning to understand how angulation affects balance!
I am going to have to play with the drills you both suggested next year.
A real of faith.
Jamt, you get me to understand one thing and then you throw out another for me! Love it!
I annotated below to check my understanding. See if I get what you are saying.
Say that you have two inclination angles where you can find balance. These two angles have different stability characteristics.
The higher (higher meaning standing up higher, not very inclined?) inclination point is unstable, if you perturb the system so that you get a bit more inclination you will fall, and if the perturbation is in the other direction you will vault up. You will have to use a lot of fine motor mechanics around the foot to stay in balance. The reason is that at low degrees of inclination (being more vertical to the snow) the amount of edge angle change will not significantly change the turn radius? Even more so if you are skidding versus carving wouldn't you say?
The lower (more inclined, hips lower to the snow?) inclination point is stable, if you perturb the system so that you get a bit more inclination the reduced turn radius will vault you up again, and if the perturbation is in the other direction you will fall down towards the stable point again. The reason is that at high edge angles (and therefore high loading), a change in edge angle will affect the turn radius more?
This is so cool, because it means that it is much easier to balance with high edge angles than with low edge angles! All it takes is a bit of faith :-D
If you fall inside from the first inclination point, you will just have to have some faith that the other inclination point will save you when you get there.
Edit: most intermediate skiers will put more weight on the inside leg instead of this faith when they feel that they are falling to the inside.
Ever wonder how Ligety can balance at a super high edge angle for "quite some time"?
PS a lot of oversimplification of course, like flat surface, ideal skis etc but the concept is still interesting IMO.
I think that means at low amounts of inclination, any change in edge angle results in less effects on turn shape than the same changes in edge angle at high degrees of inclination? Is this true? All skidding aside.
