This kind of discussion avoids the whole stylistic superiority-inferiority issue that has been such a problem on this WC/WT/VT forum lately. And it really opens up the discussion, since everybody can relate.
I get you, but I don't think it's a stylistic issue. I'm only discussing the VT system as taught by YM. If I take the cost vs benefit approach, it may cause less offense but it's also too subjective.
There is right and wrong in YMVT, both in reference to what he taught and what is functional. I've tried to make this more objective by illustrating problems that result from not getting it right, and all have acknowledged it. So, I think everyone can relate if we lay ego aside and take an honest look at things.
Everyone can test out the drill/scenario and see what works, how and why, and why alternatives fail so easily where one should not.
Also, looking at the photos I posted, even though they are still shots, with explanation it can be seen clearly that awareness of the VT strategy YM taught is missing in the latter two (three). If there is still doubt, any video or direct interaction will dispel that.
Since
wu-sau is only a small part of the whole, I think it may be a bit more obvious now that it wasn't a WSL invention. It is too cohesive with the rest of the system for this idea and strategy to have been reconceptualized into the existing actions of SNT for example, without changing anything.
If the actions are not changed, but explanation is given, then it will be evident what the original interpretation must be. Where there is strategic information represented in abstract actions meant to establish certain concepts, others have replaced this information/gap-filled with application ideas devoid of strategy.
The opening actions of SNT are a perfect example. Everyone sees blocks or strikes of all sorts, or training shapes for these types of things, or they have changed it to add rolling arms, introducing complicated double arm actions like
kwan-sau before even looking at the basic punch in the system. Very illogical learning progression and not a "little" idea.
When I look at it I see abstract concepts setting up an understanding of space and attack lines which we'll deal with when looking at the punch in the following
taan and
fuk section, which are also abstract pre-punch elbow training, not deflections and controlling arm actions. Each step of the form and indeed the rest of the system is built upon in logical progression this way.
If we look at other YM derived lineages, we wonder why all this information is missing and their systems are comparatively so disjointed and full of applications, not to mention failures we've discussed. We then look back at various student testimonials of YM's temperament (preferring to teach 1 good student over 10 lousy ones, and not wasting time on people he felt not worth it) and teaching style (having students go through the motions with little or no explanation), and the lack of fighting experience of most, and we can plainly see why their systems are the way they are.
If I tell a beginner this is
taan-sau, it means spreading hand, but give no further detail, they will naturally assume it's for blocking. If I say to them this is
chi-sau practice, it means sticking hands, but give no further detail, they will assume it is for sticking to, feeling, and wrestling with an opponent's arms.
Why else would other YM lineages be missing all the information and what they do have is exactly what an uninformed beginner would come up with?
I know it's hard to avoid offense when talking about this, and I'm really not trying to insult anyone. But hopefully I am conveying to you just why I have the views I do. That they are based on an honest examination of the evidence (technical analysis and comparison of teachings and functionality; YM student testimonials and experience or lack thereof; photos of YM showing ideas no one else can explain), and not just "because I said so".
