Re: Nice instruction video
The aikikai lineage shihan of our organisation is Shimamoto Katsuyuki 8th dan.
We also have a Hombu Dojo teacher visiting every year, Kobayashi Yukimitsu 7th dan, but he's more like a guest instructor.
I do think that Suganuma's instruction feels a bit more similar to Kobayashi's than to Shimamoto's, but I can't tell you why exactly. Perhaps it's more a matter of attitude than form. Also, my perception of form is not yet as sharp as yours.
