Gino,
I knew it was a question to provoke thought
You're also skilled in Shuai Jiao don't forget....you're being modest.
Let's put more Peas in the Pot for discussion now. My statement is this;
"You must adapt to what a person is showing or giving to you and cannot force what is not there"
You shouldn't try to LOOK Hung Gar. Yes, train bridges and fundamentals of kung fu and Gong skills and all that. But in the end, it comes downs to what is given to you...not what you WANT to look like.
A few examples:
Presentation (1) A grapplers shot (collegient level) is not some HOKEY I bend over without a set up and try to grab you around the waist or legs. Like you see in MA magazines.
It's very tactical and usually set up with a fake High in order to shoot low. A good grappler will lower his level (his hips and center) and pentrate always when you're at your most vulnerable. That is the truth.
I don't care what flak I get for this (my opinion ok) but HG is not a GROUND grappling style. It's foundation is TCMA and that is... Root throught the feet and waist and project your bridges onto your opponant. SO its and stand up style...not a fight from your back style.
What HG can do very well is trap and grapple while standing up. HG's "Hook bounce and sweep method" is the A- Typical perfect example for this.
SUMMARY: Standing you have a chance to LOOK HG, but taken off your feet... bye bye and switch methodology until you get up again.
2) If you are presented with guy who will stand up and be willing to give you something to work with...then by all means look HG as much as you want.
Now, some people who've only learned to strike and pull back again like in boxing are only using a small portion of what HG can do. These people accept using Western Boxing principles for HG fighting because they havn't learned to "Bridge the Gap"

and stay there.
Boxing "the sweet science"...gotta love it cause it works and its pure effective. But it's not deep. Energywise it's different than TCMA. If I want to stand on the balls of my feet, Raise my shoulders, Tuck my chin. Jab - Cross - Hook
Jab= hit and return to chin position
Cross= cross over the arm , shoulder , hip and raise the rear heel...and return to position
Hook= ....aaaah You get the idea don't you?
What should I call that? Modified Hung Kuen or Boxing? If I have to resort to that just to make my HK effective than i've been wasting my time as a martial artist.
So the problem lies with most that a boxer doesn't want a constant bridge. He wants it in and out to keep striking and keep mobile on his feet. What's hard for some people is knowing how to once again deal with a person who won't give you what you want. That is a clue allot of people still havn't figured out yet. If they did...they would see that everything they need for stand up is already in Hung...no need to add San Da skills.
(3)Others have learned to use their bridges differently. Like once they make bridges they are on thier opponant like a damn octopus or perhaps a tiger with it's claws sunk in and don't retreat.
Still others don't realize you bridge with the legs as well. Mah bridges with Mah...and also you have to know what direction to crowd your opponant so he always feels uncomfortable. Or suddenly yeild and borrow his energy if you realize he's too strong for you.
I much preffer that than to throw round kicks and look like Tang Po. hahahahaha
