(as mentioned before, I'm jumping in without reading much of this thread. I'm commenting for the purpose of educating any readers that are here to learn how to ski powder. Let me know if this discussion isn't germain. I'll cease posting it.
Really, I will.)
The deeper the snow, the more you need to balance between the two skis. If you are touching bottom with your outside ski, you can pretty much ignore the fact that you are in 3D snow because you have actually gone
through it and are back to plain old firm snow skiing.
The need to balance between the skis is a result of many things. A couple are:
- developing better flotation
- allowing the skis to perform similarly with regard to tipping, lateral and fore/aft balancing
The second point (skis to perform similarly) is critical in 3D snow as when your skis are plowing through the snow you need them to have similar responses to the resistance the snow is giving you. If you (the figurative you) pressure/stand-on one ski it will probably have more resistance to moving forward than the ski that isn't pressured as it is in deeper and displacing more snow. The result is the inside ski develops a mind of its own and doesn't track along with the pressured ski. In most cases this results in the inside, light ski tracking far inside the turn (divergin) and the skier being twisted around, loosing their balance and falling.
