We can give good specific advice to skiers about how they should stand. First you have to define what event we are talking about and the ability of the skier to generate release energy for a transition move, taking the body across the skis. GS really doesn?t apply here, as the speeds, forces and arcs are not in context with arc a GS ski makes or race course setting these days or speeds regular skiers use.
To use GS as a demonstration of recreational skiing approaches is ridicules and out of context. No PSIA instructor has ever made or tried to make a move at forty miles an hour, like they use now in GS. So what are they talking about? Stand wide and pivot that?s their legacy. They are talking through their hats making things up as usual.
Worst case scenario for wide stance
Intermediate skiers and aspiring experts are held back for eternity, from upper levels of skiing with a wide stance. In their case the wide stance keeps them from developing pressure and rebound for energy transitions. Once they are in the wide stance they begin relying on pushing movements rather then using bending to learn releasing energy for transition.
It takes longer to get across the skis with a wide stance and it?s very difficult to develop an understanding of outside ski balance and pressuring needs. In a wide stance when you move the body away from the outside ski to create big toe edge angles, pressure doesn?t built it moves to the inside ski.
Wide stance skiers are always twisting the skis at initiation especially when High C engagement is needed. This used to be a tactic a few years ago on the world cup, even in slalom, when the shapes first came out, but has lost favor for edge to edge tipping.
Slalom racers can?t ski fast by using too many wide stance turns, as the outside ski loses contact as the body mass moves into the arc. When the skis are wide the body moves into the arc, okay, extending the outside leg, but as it does, it moves away from where pressure needs to build. The skier looses balance to the inside ski, then the body has to be held up from falling over by that leg , the inside ski saves the develping body lean from dumping the skier.
This is a losing battle as ski pressure develops late and is usually a hard hit or edge set. You see that in PSIA instructors skiing steeps or bumps.
The CG has to stay connected with balance to the outside ski in slalom and short turns, (which for every day skiers are regular size arcs), especially in the upper third of the arc.
A narrow stance affords all the good things yet none of the bad, I don?t understand the resistance to it?
You can keep your balance well situated over and on the stance ski in a narrow stance, you can increase angles with inside leg flexing, that can be managed and timed with forces building in the arc, Developing angles while staying balanced with the ski, assures gliding properties rather then gripping..
I define maintaining balance on the outside ski this way;
"The ability to lift the inside ski at any point in the turn.. If you can?t lift it, you?re not with it. You are using the inside ski to lean on. This is out of balance." Harald
It?s also slow, creates drag, and keeps the out side ski only partly pressured.
Don?t worry you need not make it clear to me at least, that CSIA is no better then PSIA. My experience with CSIA methodology doesn?t give me any more respect for their system than PSIA?s. They are versions of each other, using the same biomechanics. Canadian coaches association doesn?t get it, either, one of our PMTS coaches was a trainer / examiner for CSCA and after he learned PMTS, and only then did he begin to realize how much understanding of technique and movement development he was missing .
That's why I have so much respect for people who are open and at least give new ideas a try!! The Epic gang unfortunately has the PSIA glasses on so tight that they can't even read PMTS and get it, let alone educate themselves with PMTS trainers. I think they are terrified, because deep down they know we are right. Isn't it amazing that they will sacrifice their own skiing to be true blue to PSIA?
Later I'll get into the wide at transition issue.
