To me I feel there is to much emphasis placed on what looks like Wing Chun for instance I can utilize a tan da, pak da, gan sau, chum sau, biu sau the list goes on forever to counter such & such. It's more important to understand the concepts & the Wing Chun body mechanics not so much using the trademark techniques to beat the opponent. (Not saying techniques aren't viable obviously, but too much emphasis would be placed on you have to do it this way or that way to look like Wing Chun)
Instead as mentioned before utilize the centerline concept, immovable elbow, mo ying gerk, straight line, hard & soft energies whatever. These are what is important in expressing Wing Chun whereas in most Wing Chun circles we can't even agree on the proper way to perform a "tan sau" Ip Man does it this way, Yuen Kay San does it that way, Pan Nam does it differently, even Pao Fa Lien has a different expression.
So I feel adhering to the concepts & principles of Wing Chun is a must & is what's truly important not so much this technique should be this way, or this footwork should be that way. (But either way when footwork is absent there is a problem lol)
Just wanted to throw that out there, not disagreeing with anyone.
