Bujin said:If Uke were to grab because he lost his balance it would be the easiest thing in the world to follow up with a throw or some other type of balance take down. Why on earth would Tori let him get his balance?
Uh, who said tori has to let him get his balance?
There are a lot of different ways to do this. Some of them are official henka, and some are the natural offshoot of the principles you find in the kata. I don't like to talk about things like this on the internet because it really can't be transmitted by words, or even video IMO.
Brian, if you get to Japan like you expect, ask me to introduce you to Kizaru. He can run you through this kata from top to bottom. He loves Dunkin Donuts French Vanilla coffee and would probably be pleased to help you if asked. He is very knowledgable about the subject matter.
