To me, the "softening" of Uechi Ryu isn't an act of commission. It's one of omission. In other words it's all there in the kata, but we spend most of our time in kumite and bunkai working on basics. It takes a while to get this stuff... But once you learn the basics of human movement, then you can add spice to the sauce.
I think the reasons most people don't see the Nasty in Uechi is because of the following:
* They do lots of sport sparring, and think that's the end point of their training.
* They don't develop their Uechi hands and toes.
* They never investigate the grappling half (yes, half) of Uechi
You can get pretty addicted to "boxing" Uechi style, and do quite well in a fight I might add. And with that addiction, you will neglect the essence of a style that never even had a seiken fist in the first place.
And why would the original style not have a seiken fist?
I never worried so much about "lost" aspects of Uechi Ryu. If you do some kind of grappling art (aikido, jiujitsu, judo, wrestling), you work your hands and toes, and you study kata applications, a lot of this stuff IMO just falls in your lap. Then you listen to people describe "lost techiques" in the system, and what they describe fits into what you see as an obvious trait of the system. IMO, of course...
One thought to share... My Goju/aikido/greenberet instructor had some interesting "halfway" measures for applying the Nasty in the fighting arts. For example, I can reach down and grab someone's gi right around their adductor muscle and just barely miss the gonads. But when you shoot down, smack, and grab the gi down there, your partner gets the point. And it does make for a nice "handle" to dump the person.
The rest you leave to your imagination.
I agree with the philosophy of Master Tosh that one needs to get a little Nasty now and then with this stuff. In class, I call it "tasting the hot sauce." For instance you don't need to hit the neck with your hirakens very hard to: 1) make the attacker crave hitting harder, and 2) convince the defender that this stuff really works.
As for the clothing... I love my Kwon "self defense" gis. They don't snap pretty like a Tokaido and they don't hold up quite like a judogi. But they do take a beating with the grapplers and don't seem to tear. My old one had belt loops on it where you could wear a real belt (for reality-based training), but they don't do that any more.
