Like someone said prior in this thread (I don't want to research, but the statement was very true). The most WC move of all is bringing a gun to the fight. It's very true. Sure theres no honor in it, but hey...you win
I'd rather fight so I would never use that tactic. But it is the most efficient and very direct.
Good pont, this is why Wing Chun is not this move or that move, this hand or that hand, or this utilisation of this principle in that situation. If there was one founding principle that I would say is essentially wing chunI would have to say the principle o effeciency, i.e. Achieving the most with the least effort. The problem with many arguments about Martial Arts, IMO, is that people are always saying "no in this situation, you would use this move, or you would do this" "no, no you wouldn't do that, you would do this or use this" and back and forth it goes, with no resolution. It reminds me of the story about Wong Shun Lueng who wasas in a restaurant and was being pestered by the owner of the restaurant, who was saying to him, "If i did this what would you do, or If I did this what would you do" finally Wong man said to him, "I dont know, why dont we go outside and find out".
The point is this, if you need a hook use it, if you need a Tan sao use it, use whatever is at your disposal, it is important that you find freedom from the art, and do not become a prisoner to its form and structure, this is of course the art of artlessness, and was the key reason why Bruce wrote the Tao Of JKD.
Whilst I appreciate the structural differences between a boxers hook and a "Wing Chun Hook" and the contrasting principals that come into play, there is a need to understand that all Martial arts are not and end to themeselves, but are a means of enlightenment, of understanding, yourself and those around you.
That is why when talking about who has the best style, is it Moy Yat or Choi Sheung Ting, or Derek Fung, is to a large degree irrelevant, because their style may be the best for you at that time whilst you are on the journey, then as you being to think and grow you being to spread your wings, trying out other styles, other ways of understanding the martial arts and ultimately understanding yourself in the process. perhaps from there you will come full circle and begin again with Wing Chun that is an individual choice.
The only thing further I will add to the current disscusion is this, muscle memory is a very keen animal, and once it is engrained it can be very hard to unlearn what you have learnt. In some cases, with particular martial arts, you will find that it is a requirement to unlearn what you have learnt, otherwise you will impede automatic timing and learning. An example of this is when I started Traingin under Sifu Fung, I was so deeply ingrained with JKD that I automatically fell into the fundamental concept of "blading" instead of the squarre on stance of Wing Chun, this was an element that I had to unlearn what I had learnt. (By the way, there is a form of blading in Wing Chun, but it comes from a totally different premise as that Of Wing Chun.)
Whatever you do, and whatever art you choose, make sure that you absorb it, understand it, apply it, learn from it, and contiinue to grow and expand within it.
