I think you're correct, Andrew. I've often lamented...when I was active in Gracie JJ, I was one of maybe 200 people in the U.S. who knew enough to work it. Walking down Main Street, Huntington Beach, surf punks were just targets with ego's, and no technology to back up their attitudes. Now, with so many fight academies around, and guys teaching their buddies in living rooms during UFC's that have been around for so long, everybody seems to know a little bit of something about superior positions, and laying down some ordnance from them.
I used to include some BJJ for my kenpo students as an adjunct for kicks & giggles; now, some of the vertical and horizontal grappling issues MUST be addressed for simple parity with the rats on the sidewalk.
I personally think some techs need to be seriously revisited & revised to reflect the changes in the personal combat zeitgeist created by the success of MMA events. Thrusting Prongs as a kenpo tech against a bearhug was an OK response when people grabbed you Wild Wild West style in bearhugs and tried to pick you up to sling you around. Now they shoot on you & clinch you. But the opening aspect of Thrusting Prongs...having the arms between you and the opponent and splitting your legs by stepping back into a forward bow...are close enough to getting an arm in for a sprawl, that it could be modified...deepen the rear-leg in the forward bow and drop the height while you pop back and straighten the arm(s) you have between you and the bad-guy, and you're now teaching something applicable in 20XX, versus 19XX.
When last I bounced, the only grapplers out there to worry about were freestyle wrestlers, and they kept giving up their backs; easy. Not anymore.
In the 154 tech EPKK cirriculum, are any listed as defense against a double-leg? What about a Muay Thai neck-wrestle clinch? Or a knee coming up at you from within that clinch? What about those nasty Chai Sirisute inward slicing elbows from that clinch? Or a head-butt? Nope. But I have some lousy Ram techniques I can try to tweak to make work on a double-leg take or shoot, originally designed for an unsophisticated bull-rush tackle by a half-drunken oaf.
IMO, what Parker did that was brilliant with the motion model, was to attempt to devise techniques against likely attacks from his era. Boxers, judo guys, thugs, etc. Concepts and principles of motion defense, applied to common attacks of the day. Some are still universal; there will always be some guy trying to take a poke at your melon, and those skills are often under-emphasized in a kenpo land obsessed with where on the clock to step in a wristgrab defense. But what's missing from the main body of kenpo training are solutions for stuff guys today are going to try to throw on you. Few, if any, are going to try to get you in a full nelson, but we have a couple techniques against it, just in case. Nobody trains in applying full nelsons, at any school I have ever worked out at. Even the wrestlers I've hooked up with don't go for those, or train for them.
In contrast, almost everyone now has learned how to go for shoots, clinches, and even some standing chokes (guillotine, hadaka-jime). Locking Horns isn't geared effectively for a guy who has you in a true guillotine, and the mechanically unsound single leg take embedded in the SD tech will only place you in the guys guard and get you stretched out while you pass out. And I challenge any AK guy out there to name an SD tech in the 154 system that's against a rear naked choke, standing, seated, or supine. OK...add prone, just for kicks. It ain't there. But untrained Joe Blow's are learning how to do these things; I trained the son of a recently deceased buddy of mine back in 2001-2. When I went to the wake after the funeral last year, the little gang-rats he hangs out with were doing our moves with each other in the garage. They had been working them, having gotten it second hand from the kid, and figuring the rest out from UFC re-runs.
Mr. Bishop mentioned passing whole systems on intact, and availability for promotion within the system. As a kenpo practitioner, it's been over 15 years since I worked on the AK long forms...I recognize them, and partially remember them, but the idea of spending hours ironing the kinks out of Form 5, 6, 7, etc., so I look really pretty doing nonsense is a profound waste of time. I would rather spend that time working solutions against a clinch, shoot, etc., and getting down my responses to a broad tire iron or ball bat swing, instead of Finger Set with foot maneuvers...things that we're starting to see more of as a result of the times. As a kenpo instructor, I cannot -- in good faith to myself -- teach that to future students with a straight face, telling them it's going to be OK. It's a lie, and I won't do it. As a kenpo black belt on a life-long journey, it means I will never see a promotion again. I have abandoned the core cirriculum around which promotions take place, and there is no Senior in front of whom I could test and have what I do recognized. They'll call out an advanced form..."Sorry. Don't do that one; waste of time." They'll call out a technique against a rear full nelson..."sorry; don't do that either...it's a stupid technique against an unlikely attack, and a waste of time to practice, so I threw it away". They'll call out Five Swords with extension, and the extension I do will be to throw him to the ground, kneel on him in a knee-up position, beat the hell out of him, then finish with an arm-break accross my thigh...not the EPAK extension the rest of the kenpo world is familiar with, but one I feel will better serve my students by giving them better tools.
So, my career in kenpo is done, in terms of eligibility for advancement. But at least my guys will be able to fight.
Sorry for the rant, but this is a thorn in my craw on an ongoing basis, and has been since the late 1980's.
Enjoy,
Dave
