>... Pressure - you must balance forces. This is done with the base of the ski. The "edges" just help slice into the slope so the base can do it's job. ...
This is nonsense. Don't you remember that I showed mathematically that both the sides and bases of skis experience perpendicular (aka, "normal") forces from the snow. In some situations, the sides of the ski actually experience more force from the snow than the base. In other situations, the base takes more of the load. The side load is rarely zero. This might happen if the edging angle suddenly becomes less than the critical angle and the ski is about to fall off of the little shelf in the snow that it had previously made.
If you re-read the old thread to it's completion, you will see that after I presented a detailed analysis and related graphs which showed the forces on the sides and the bases in various situations, even daSlider himself conceeded this point.
Of course, like other posters one might encounter on the Internet, daSlider never actually admitted that he was wrong, he just stopped making silly pronouncements about this particular area but kept the thread active by moving on to other topics.

When it's pretty clear that not everyone will agree with you on some point, don't you think your comment(s) would sound more realistic and moderate if you would instead phrase them like this:
, Daslider's title was correct and simple and obvious."
--------->... The idea that you always get better grip as the angles increase if false. Many other factors come into play ... the majority of the thread was all over the place ...this thread has a long way to go to catch up with that one....
All absolutely true statements. In fact, I'll go you one further - statements that use the word, "always", are almost always wrong.
See, we occasionally agree.
