Hi Ten,
My take on it:
Due to (then) modern societal adjustments (of which everybody is already aware), the importance of maintaining private security forces in a state of combat readiness became de-emphasized. This gave the
Gung Fu teachers of the day two options: "put on performances and like it", or "quit"...
Because a two-man choreography (rather than
Saan Sik/ "Application Breakdowns") was important for
Biu Yin/ "
Gung Fu Demo" purpose, LSW's two-man choreography was the
Gung Ji Chaak. This was their ONLY bare-hand
Chaak, although they had some weapon
Chaak as well...
Lam Cho grew up in that school, taught and practiced
Gung Ji Chaak for his whole career. Later, he incorporated some
Pek Gwa weapons, designing several other
Chaak as well, including
Fu Hok Chaak...
By this time, students who performed were good and ready just to have something "just a little different" to perform. This, including a number of LSW
alumni who remained to train with their
Hingdaai Lam Cho after the passing of LSW...
So, I'm not disagreeing with your observations. In fact, I don't particularly feel that "stepping back three times", letting someone "push or knock you to the ground", or fancy, "360-degree floor sweeps" are any kind of practical training either, especially just "as-is" (as, in a two-man set)...
I disagree that removing "all the 1-2-3, 1-2-3..", "jumping", and "spinning steps" of
GJ Chaak is any type of
practical improvement...
I will, however, mention that unless somebody is able to get accomplished through such two-man choreographies what many of us can, they might do well to avoid selling themselves short through a leap to judgement, lol...
Respects,
Michael
