The reason is that unless both fighters have very good technique, a sparring session becomes about 'winning' and not about improving technique. Randori within Genbukan is only done at higher levels that have proven they have good technique.
I don't believe that. Sparring is about whatever a teacher reinforces in his students. If he touts it as a tool to develop technique, that's how it will be viewed.
In fact, I think that idea is actually
undermined by this policy of only having higher ranks spar. Because, by then, two things have happened: 1) the person has developed a reputation as a skilled proponent of his system; a reputation that stands to be tarnished in sparring (because, let's face it, everyone looks bad in sparring at one time or another) and 2) people develop a sense of technique based on more ideal circumstances; a sense that comes crumbling down once sparring is finally introduced.
To my mind, the sooner sparring is introduced, the better it serves as a learning tool. I believe a lot of the bad sparring I see stems from the mental hiccup people get when their technique doesn't look and feel the way it did in line practice, pad work, or kata. The earlier they get to grips with that sense of dissonance, the sooner they start to internalize a sense of how it will actually feel in its less-idealized state.
Also, by using sparring as a learning tool early on, you establish that sparring is the laboratory. Not the showcase. Less ego involved when everyone in the match understands that they're still in the process of developing the tools.
I am not afraid of randori, but I flat out refuse to fight full contact.
I am a software developer / systems engineer. I need my brain. I am not going to let people pound me in the head for no good reason. I had a severe concussion once in my life, and that was enough. Accidents happen during partner drill and resistance training as well, and I accept that. I am just not going to invite it.
Who said anything about full contact? I'm a former writer/editor, former counselor, and current stay-at-home dad. You don't think I need a brain?
First of all, people have the option of wearing headgear and gloves. I sparred in boxing and can still form a coherent sentence. I competed in full-contact stick sparring under the WEKAF format and can still walk a straight line.
But the OP never even mentioned full contact. They just said sparring. I personally was intimidated by sparring, even the comparatively light contact sparring we did in taekwondo. It was simply the feeling of being in direct physical conflict with someone else that bothered me. Level of contact was inconsequential. Being matched up
against someone else was enough to make me very uncomfortable at that age.
Conflict often makes people uncomfortable, even without the threat of physical harm.
And if some people label that as fear: whatever. Being able to sit behind a computer screen 12 hours per day without a headache and providing an income is higher on my priorities list than being a tough full contact fighter.
I'm not a tough full-contact fighter. I spend my days changing diapers and steaming carrots. So there's no need to be defensive about this. As I said in my previous post, you've misunderstood my point here. Okay?
I don't think we're actually in nearly as much disagreement as you seem to think. Cool?
