Flowing COM mess and the quicker picker upper- Arc TechCodyblank, Arcing (carving) is as easy as walking. In fact, many of the movements are the same. The modern shape ski promotes/enables this crossover of familiar movement patterns.
You do not need to concern yourself with the location or movements of your COM to be able to ski the way you want. The COM question is a course of study in and of itself and if you are so inclined (pardon the pun) it may be of no harm. BUT, you don't preoccupy yourself with internal dialog concerning your COM while walking, running or playing. So free yourself to enjoy the unique and seriously fun sensations of Arc2arc skiing. How?
There is an article/document in the supporter area called Arc Tech. There is a wealth of info specifically focused on arcing. I suggest (to avoid info overload) you read the intro then read page 2. Go to page: 12, 13, 14, and 15 to look at the Phase Photos. Take those images and the bullets above each photo to connect each phase. BTY, download the PDF it is much easier to deal with when reading.
Arc Tech is a "living document." In other words in its entirety, it still needs work. Don’t let that stop you, it is complete and of great value to anyone looking for the "How and What" of carving/arcing.
I see now that you are not a supporting member, you will not be able to view this work. May I suggest to become one. I did, and I benefit from it every time I log on to Epicski. I am not kidding. In case you are wondering, I profit in no way from this "sales pitch." Bolter
