It turns out that aiki sword technique and iai sword technique are vastly different. How do I know?
Well, while the rest of the class were practicing kata, I was just working on the basic draw-and-cut. Then I just started doing cuts - high, mid, low.
Sensei walked over and said in a tone of voice like you might use with a wheel-chair bound Special Olympics athlete trying to do a pole vault, "Oh, that won't work at all."
Anyway. Three hours of class. The style is very different than what I'm used to, but it was a heck of a workout and I'm glad I'm going to get back in both practice and shape. It will be good to be sharp again - focused, centered, fit. This style is much more "soft" than Ki-no-Kawa. That's neither a good or bad thing, just different. It depends more on a cooperative uke, but this also means that uke has more to do. Since we spend at least half our time as uke, I'm sure I'll learn a lot about leading and following with attention, rather than muscle and leverage.
I did something bad to my bum shoulder though, (probably my thousand practice cuts...) and today I have perpetual dead-arm in my right arm, like when I sleep on it wrong. Only it's not waking up. One hopes this isn't a permanent condition, it turns out that although I'm nominally left-hand dominant, I do almost everything right-hand dominant. Simple tasks like shaving and brushing my teeth are rather hard.
I think the gym and the hot tub are calling to me tonight.
