John,
This is an old conversation for many of us...
Too many organization, in their quest to build a better curriculum, simply go out and learn a new hyung/kata and introduce it into their curriculum.
They don't have a deep understanding of the hyung/kata that they are already training in but they are interested in filling their minds with still more memorization of techniques that they don't truly understand...
I was in the Federation in the early to late 1980's. I learned the first four Chil Sung Hyung, but not the last three or any of the Yuk Ro hyung.
When I learned Chil Sung Il Lo hyung I learned it with a heavy Tai Chi flavor. When I trained with KJN Andy Ah Po in September, 2005 at a seminar that we taught in Arizona for KJN Darryl Khalid, he taught the hyung as if to be a Tang Soo Do hyu doing a Chinese hyung. The flavor was considerably different from when I first learned it in 1983.
The hyung (all of them) have gone through changes over the years, but the most upsetting thing about them is that when they were taught by the Federation, like all hyung taught by the Federation, they were taught either without any Bunkai or with Bunkai that was useless.
When I meet with others and we train on hyung/kata, as you know, the hyung start to come to life because the Bunkai is real and works...
If you had been taught the Chil Sung and Yuk Ro Hyung with proper Bunkai you would maintain them. No hyung/kat is worth learning or training with if you are not taught them with the correct flavor and without real Bunkai...
I had the pleasure of having JB Yager participate in a seminar that I taught last week at "Red Lion Karate" in Red Lion, PA. You met Gene and Amy Lau (the dojang owners)as well as JB Yager at my seminar back in February. At last weeks seminar JB Yager asked me to demonstrate Chil Sung Il Lo hyung. When I finished JB exclaimed; Now that is how I always invisioned that Chil Sung should look!!!
As you know, JB Yager is a practitioner of "Iron Wheel Fist". This system is Korean, but is not a "Karate-Based" system. It is more of a "Shaolin-Based" system. Having a good understanding of Tai Chi and other Chinese systems, JB exclaimed that; everyone that he has seen perform these Soo Bahk Do hyung has performed them as "Karate guys trying to do Chunese technique". It simply doesn't work (for me).
If you are going to learn a form, take the learning deep. Establish an understanding of the principles and concepts within the techniques. Don't just memorize the order of the techniques and determine that you now know the form.
Craig,
Learning a hyung simply to say... I know that hyung!!! is a waste of good training time. Don't get caught up in volume. It's the wrong way to train...
