OK B....my counterpoint...you stated: "B. Tipping to turn works on hyper sidecut skis, in more open places but DOES NOT work in real terrain, in real conditions, on real skis"
I believe that no matter what skis I'm on or what snow or terrain I'm turning...I use tipping motions to the outside edges of the skis...even feathered. High edge angles are best kept to groomed snow but the use of drifting or sideslips or whatever it takes to enter the next turn in off piste terrain still uses some transition to an edge and for me...that's tipping. You stated this pretty much in your first paragraph so I was a bit confused.
Tipping and maintaing edge angles is NOT easy for many to learn and once learned IS a mastery of at least that one component of skiing. But it is important that if a skier wants to be able to move off of groomed snow and into off piste conditions, they have to open their minds, watch and learn what those who have mastered to ski the big bumps, steeps, crud, pow etc....if they too want to be able to ski this terrain. Keeping an open mind and willing to try new ski skills is the only way that's going to happen.
As far as "dogmatic ski choice"...I would say that in most cases it's not the ski choice that limits the skiers ability to learn new ski skills. AND what works for you, me or Mike might be completely different. Unless a skier get's a ski that limits their abilty to improve by being to long or to stiff or if the binding is not placed at it's optimum position, the ski is only part of the equation.
Mike...certainly PMTS is NOT one dimensional and I didn't see B state that....I think that those of us who have experienced PMTS clinics realize there is a fantastic foundation to great skiing in that program...not just limited to edges, pole plants, free foot, hips...etc etc etc. But I DO believe that to ski off piste condtions, the discovery and use of additional tools are required.
For me my exposure to guys like Harb and Clendenin has been a truly remarkable experience and continues to open more of the beauty of skiing All Mountain.
