Fundamentally, they are all the same, but many characteristics evolve due to speed and pitch (and the enhanced forces that result), and skill and sophistication of movement. It's very much like the progression from crawling to walking to running.
I fully expect some controversy!
Nice illustrations Bob.
I run the risk of being chastised again, but here goes.
IMO this unbroken line of development is flawed. The OP wanted to learn to a2a. Bob your progression from wedge on up stops short of his stated goal and in fact makes a2a very unlikely to ever happen, impossible really. I assume (ass of U and ME) that your dynamic parallel is not a2a but is brushed/shaped/scarved somewhat. Even if that is your movements for a2a,that doesn't change much.
The subject was addressed in the (TTT) three turns thread.
Several questions were left unanswered, here is one.
Dynamic parallel turn illustration # 5,13 and 21 show CM inside of both skis yet no edge angle. How, why?
