The idea that you're going to "fade back" with bong-sau, and then laap-da them is already quite a stretch.
---Boxers do an "evade back" to avoid straight punches all the time. I just included the Bong Sau. Not a stretch at all. In fact, it kind of makes the standard "evade back" a little safer.
You included a step straight back while lifting your elbow up to shield yourself as a primary response to a straight punch then countered with
laap-da, and then another follow-up.
If you try this against someone advancing with some serious punches, I think you won't get past step 1.
----Committing to muscle memory a fast combination that is a reaction to leading the opponent to present an opening is a useful behavior.
Only if it were a practical combination. I don't think it is.
Multiple Bong Saus over and over with switching from side to side is not.
Of course not, if you don't know why you're doing it.
---Nothing at all "unlikely" about flowing with the hand in a lower position such as a Bong Sau to a strike to the face that prompts the opponent to bring his rear up to stop it or get hit....and so leave an opening lower. That's pretty basic.
Has this combo ever been pulled off for real, or are you just imagining it'd go as you think? (Rhetorical question)
And the "opponent" is detraining responsiveness in the arm that goes dead from being pulled.
----That is a valid point. Right now we are viewing more like hitting the focus mitts, but a little more realistically since you have a real target and a real reaction from the partner. But I was only showing a very basic level drill at this point. I will likely elaborate on it later.
It's one real reaction and then non-responsiveness.
To elaborate, are you going to make him respond to that, and then you have to do another step?
Sounds like you're on your way to making
laap-sau "sections", something which you criticized as too "elaborate".
---I understand just fine how it is used in both Pin Sun Wing Chun and TWC. But maybe not in your WSLVT since it seems to be so special and completely different from everyone else's Wing Chun!
It's just that what you know from those lineages seems to be the equivalent of only knowing
pun-sau and saying now you're going to make modifications to "
the chi-sau drill".
