1. Find someone who actually knows aiki
2. Find somone who can and will "actually" teach
Shioda is among the few who knew how to do aiki. The very fact that he is so "different" to you? Pretty much says it all. The real daming statement is why in hell is no one teaching these things in clear, concrete, terms to train in? It's all vaguries and trial and error. Most are looking to low level teachers who really don't know, or to real master who simply won't show.
"No one?!!?!" Are you telling me that there is absolutely NO ONE on the East Coast who meets your criteria???
Say it aint so....
