I see what you're saying. But I'm wondering if just doing the Gor Sau & Lat Sau against partners feeding something other than Wing Chun might be more productive. What you describe sounds like a pretty involved process to me.
It certainly would be productive to do as you say, and you're right also in saying that the process we have in the LT system is "involved."
But before I came to the LT system, I trained another Yip Man lineage system. They had no sections, though you did learn a few basic Chi Sau partner drills. After that, it was all about playing freely (Gor Sau).
To be sure, some of those guys were pretty good. Still, I felt there was something lacking in the Chi Sau there. People who were higher graded than I was, were better than me (duh!
). But I always wondered
how much better: they did exactly what I did when Chi Sau'ing (so pretty basic attacks and an over-reliance on Bong/Lap
), only they had more experience with it than I did.
From meeting some LTWT guys, and doing some Chi Sau with them... well, for me it was like chalk and cheese. They seemed to have a far better understanding of using their system's principles and body methods in their Chi Sau (and also in their Lat Sau, of course). The forms are full of so many things (techniques/motions, body methods, concepts), and the WT guys seemed to be able to use that in their Chi Sau. And use it fairly instinctively as an exchange developed.
In my earlier group/organisation I was at Chum Kiu level (knew the form, kinda sucked at it), but when I Chi Sau'd with that group's instructors (who also knew Biu Tse and the Dummy and had far more experience with CK), none of that knowledge seemed to come out.
Doing well against them in Gor Sau was a nice stroke to the ego, LOL, but I always had this nagging thought - I knew that I shouldn't be doing quite so well against them. If I've trained for say 3 years, and they've trained for 7 or 8 years... things should be far from fairly evenly matched in Chi Sau (IMO).
So I agree that it is not an absolute requirement to have sections like the ones LT came up with, but they do offer something really valuable - they make sure that students are understanding how to use what is in the forms when they Chi Sau.
Of course, the sections are largely WT vs WT. To me that isn't really too much of a problem. At a Chris Collins seminar last year he made an interesting point. Essentially he was saying that when you Chi Sau don't worry too much about what a boxer would do, or a Silat guy, or a Karate guy. You're a Wing Tsun guy, so focus on using your system. An open line of attack is an open line of attack - regardless of who is in front of you. A bridge is a bridge. Keeping forward pressure and intent should be used whomever you are fighting. But, essentially, the Chi Sau sections are not about as-is applications you would try and use specifically against a certain attack (or a certain type of attacker - e.g. a right cross from a boxer). They are more about understanding how you use your Wing Tsun.
