BTS, You are one of the persons with the best understanding of ski technique on epic IMO and I have learned a lot from you, but on this one I think you got it reversed. Say that I balance completely on one ski an that the balance point is in the middle of the ski. To achieve this position the body is somewhat angulated and the CoM located somewhere around around the belly is straight above the middle of the ski. However if I want to move the balance point closer to the edge I need to reduce this angulation, or move the upper body closer to that inside edge. If the ski is wider I need to "de-angulate" more before the balance point is at the inside edge.
Another way of moving the CoM is maintaining the same angulation and incline instead. With a wider ski I need to incline more before the CoM is straight above the edge and thus the edge angle will be higher with the same amount of angulation on a wider ski.
I'm sure I don't have it reversed. Wider skis need more angulation to balance on the edge.
Maybe we will just have to disagree on this one.
