Josh drew my attention to an old post of mine.
It applies to the discussion at hand.
It's pointless to try and convince everyone. At a point you need to concentrate on your self. Perhaps some folks are getting a clearer understanding of why there all these stories of man going off to train alone and they coming back "masters" with a vision.
So why consider leaving Aikido? Change just you!
There's no point in driving / flying out to meet certain folks if your not going to do the work when you are alone. The real test is going to be finding folks who will train and focus. This training is harder in the sense that it requires an active mind in prolonged training. We have a saying that "The mind gives out before the body." It sounds perfectly goofy to say in writing-as do the descriptions of what the mind is doing to the body in the first place. It also sounds goofy to say "You sweat your butt off standing more or less still." Or "Wind through the body." But to those who have tried to do the work-they know exactly-what we're talking about.
The first order of business is feeling it first hand and having it explained to you, then training at home alone, then going back to train and test and correct, then back alone, and so on and so on. At a point in time you will say "My body is changing" Its just the way of it. At least I can say as much as you power lift your body will strengthen-as much as you body condition internally -your body will strengthen as well. And your sensitivity will go through the roof.
"Going back to do complex techniques?" complex techniques really aren't budo to begin with- and never were. They are an artiface, an after effect of too much dojo training. That said if folks get their jollies by doing them, yes, they will be easier. In fact drawing-in and gaining a magnetic feel as the opponent is drawn to you will increase with this training. You're really controlling you and just being you not trying to really control them. But even with all that- I always advocate simple techniques in budo.
It may still be brighter days ahead for those seeking the heart of the old budo.
