OK, I promised to contact the clinician that suggested that the tips are equal at the fall line.
And I have.
After getting past "quit looking at BB's turn diagram pictures because they are wrong" and "the wedge turns are pushing out the heels" and "the wedge christies are stem turns" we have not come up with anything that supports the claim of equal tips at the fall line. The only thing that it seems targeted at is not letting that inside foot get out in front so that you lose shin-tongue contact. We have agreed to not think about tip lead and where it occurs as others here have suggested and get on with other things - like just skiing. Equal tip lead anywhere is not a goal but an outcome, an instant in time as a result of other movements.
In the discussion, they indicated that Ron Kipp, the USSA Director of Education made mention of this. Ron is/was apparently also a PSIA Examiner. I googled him and found out that Ron recently wrote a book "Alpine Skiing" (Sept. 2011) so I bought it and read it. Found some stuff I just don't agree with like
pg. 114 "the wedge is an action with the heels pushed out" and "brush the heels out"
push out heels vs guide/steer/twist tips in?
pg. 139 "pivit the skis from the tip so that the skis become parallel, almost as if someone drove a nail through the tip that you pivit from while you bring the tail into the parallel position."
pull the tail in?
And his ALL has a tall in it!??! You got to read the book for that one.
But anyway, on to our point - tip lead.
Ron does talk about it and here are some key quotes from the book (in blue).
The ankle flex establishes the posture for the rest of the body.
Stand on the slope with the skis perpendicular to the fall line.
Shuffling your feet forward and backward, you can adjust your ankle angle until you arrive at a position in which both angles are equal.
When this is achieved, the uphill ski will be ahead of the lower ski. This is ski lead.
The goal is equal ankle angles. When the ankles have equal angles on the slope, the resultant posture of the hips and shoulders is also physically facing or biased down the hill.
This answers a common question: How much should you face down the hill? The answer is based on the ankles.
Having equal ankle angles results in a lead change, that when replicated with parallel hips and shoulders, determines how much the body should be facing downhill.
A common problem is the skier pushing the inside ski forward. Skiers do this for several reasons, none of them good.
Place the emphasis on equal ankle flexion and the ski lead will take care of itself.
Concentrating on the ski lead is placing the cart before the horse.
Awareness of the ankles will result in the appropriate amount of ski lead.
Seems pretty clear what he wants to focus on. Nothing about where in the turn we might see equal tip lead however and in fact, what he says taken to the fall line reinforces that the tips could not be equal there.
So, from equal tip lead to equal ankle flex. This is the first time I have heard of this but then I'm the old new guy here.
What are folk's thoughts on equal ankle flex or should I start a new thread with the question?
