Nice video. The problem is that aikido looks clumsy at first sight when you apply new ideas into aikido. One of my teachers said, 'make it smaller and smaller unitl your partner can't notice it'
If you initiate shintaijuku(right?) when uke grabs your wrist and if it's very small and hard to notice, that's real atemi IMHO. I'm working toward it but still quite hopeless. he he. Personally I'd like to keep Akuzawa secret though he's very much open. But the attitude of 'we also do it' or 'it's also in aikido' make him secret. he he.
