Well, it's no surprise. Wing Chun is part of my martial makeup, as much as Pencak Silat, Kali, or any of the other arts I have seriously trained. If you look for the principle behind the technique (something I try to stress in every video) and not a comparison per se, you'll see that the majority of Martial systems share much more in commonality than they do in contrasts. If you were to define my art in broad strokes, you could say it's Wing Chun without body structure, It's Silat with an abundance of sensitivity and centerline use, it's Kali with close-quarter techniques, it's sloppy Pa Kua, it's flowery Kuntao, etc. I've heard dozens of labels, and I think that a person who is skilled or knowledgeable in one or two particular arts will see the nuances of THAT art in what I do. Therefore, a Kuntao guy will say something like "It's mostly Kuntao, with some Silat". A Silat guy will say the exact opposite. You gravitate towards what you find familiar in the movements, something that looks similar to what you do.
I don't see it like that, at least not anymore. I see Martial Arts the same way I see aromatic spices: I'll use what I need depending on what I'm cooking. I know what I'm doing with my Cumin, Coriander, Saffron, Turmeric, Sambal, fennugreek, etc. I know which ones to mix in what order to achieve a certain outcome. So this is my art: I know my uses for Chi Sao, Sapu, Centerline training, Suliwa, Jointlocks, chokes, body english. I am intimately familiar with the advantages and limitations of each technique, I know where it will succeed and where it will fall down. I know how to mix and match them to achieve the results I'm looking for in combat.
A good analogy I once heard (and promptly hijacked) was: "Master each instrument individually, and you will automatically know how to play them in concert." I see Martial Arts this way as well.
Using the above cooking reference, I wouldn't be a very good curry chef if I subscribed to something like "I am strictly a Cumin and Lime man" or "I only use coconut milk in my curry". These ingredients are fine, as they stand, but they are not the-all, end-all of curry. Or cooking, for that matter, and it's a very poor chef who allows himself to become so tunnel visioned. So when I hear people say "I am strictly a Wing Chun man", I tend to think "your curry is only going to have one flavor." Not a bad thing unto itself, but it supposes a mind that cannot think beyond a certain range. You can find people who will come to a point in their training where they are confronted with a choice between critical thinking and following the gravy train, and the first thing you hear from them is "Baaa".
It's not difficult to achieve the kind of freedom I am promoting, by the way. We only say it is, and add unnecessary stress and hardship to a simplistic matter, because we think "that's how it's supposed to be done". We can just as easily say, "I am a complex individual with an advanced capacity for communication and comprehension. I can judge what is sensible and what is not."
Of course, I have to warn you: If you do that, well...
...It gets pretty lonely on this island!
