Most skiers develop early angles then stop tipping, to make it worst they think they need to straighten the out side leg, which just makes the ski bounce or chatter. You saw that in almost all the skiers in this run, except Anna.
Tipping your leg isn't a position, it should be a continuous movement. First with bent legs, then with hip counter, then more lower body tipping and relaxing. It's an intricate set of movements and combination of relaxation and foot and ankle lateral movements. I'm not saying it's easy, or everyone would do it. Hirscher isn't as supple at it as Anna.
It's not your weight or your size either, that makes a World and Olympic champion. Anna Fenninger is the first to win both, back to back. It's her ability to tip her skis, relax her legs and flex to in crease the ski angles and absorb the energy, that makes the difference.
PMTS trained skier shows angles developed in turn through relaxed flexing and tipping. Not with extension and rotation.
