I vote for choice A.
But doesn't have to boxing. First you develop a base in a style...then you start getting bored...or maybe you don't think you're thy good. So you decide to attend a seminar or a class in another school. This school teaches something totally different from your wing chun. You practice those moves for a while and you notice(pay attention because here comes the most important part) that you feel ALIVE. You feel passionate about your martial art again. When you work out with your old classmates you're moving slightly differently and they comment, "Hey, SavvySavage, something is weird about what you're doing. How come I can't hit you the same way as usual?". Trying something new makes you motivated. You then combine the new with the old Like Optimus Prime combining with Megatron to form Supertron. I'm not a transformers geek but the analagy works. This same situation can also apply to visiting another wing chun school.
The negative about this situation is WHEN the person comes back and starts spouting the new philosophy he learned at the other school like everything he learned prior was BS. That's wrong and shortsighted.
I can't believe I'm about to say this. Seven years ago if I saw a comment like the one I'm about to type I'd go nuts and type back an angry reply to rebuke it. This is so funny. Here it goes: If pure wing chun is so good than how come none of the pure wing chunners ever put up videos showing this so called pure wing chun during SPARRING?!? It NEVER happens. The pure wing chunners are talking up a good game but it's all intellectual bs. I sound like Ray Pina! The people I'm talking about are happy to put up vids of static drills that only work when the attacker is cooperative. In that case I could "show" that monkey boxing works.
I'm shocked that I just said the above but this is where my training has brought me. Show a "pure wing chun" sparring vid please and shut us all up.
I really likes the vids of Victor. It showed how the human body moves when under pressure. I say it's impossible to make the body totally move in a stylized wing chun way(or any traditional Chinese style for that matter).
