To my surprise, the solution calls for 1.5 degree shims, placed with the high side to the outside of the ski - the opposite of what I've been doing. If correct, this would add edge angel to my skiing, and, help me gets better tracks on hard steep snow.

If you are knock-kneed then you should already have plenty of edge.  Knock kneed people have the center of mass of the knee inside (of ideal) and therefore get too much weight on the edge and have trouble releasing the edge.  In fact, wider skis can actually help a knock kneed skier by getting the edge of the ski even farther inside than their center of mass. (HH ACBAES book 1, I think)

Putting a shim on the inside would have seemed to be the right thing since you want to shift the center of mass of the knee to the outside. Putting the shim on the outside would seem to be an adaptive move but not a corrective move.

And that's about all I have the guts to say about that -- I'm way out of my pay grade.
