Re: Ki Aikido
For what it's worth on Shiohira sensei.
Other than some breathing exercises, which would qualify in my opinion, he seemed to be mostly devoid of ki stuff the couple of days I dropped by. From what I know he used to be Ki Society and now runs one of the 19 different, or thereabouts, organizations which can be found in the Bay Area.
At the risk of overgeneralizing, ok I am overgeneralizing, I'd say he was more grounded than most of the Ki Society types I've run into. Of course your mileage can and will vary.
Heck of a nice guy and very down to earth. I'd recommend him to anyone who happened to be in the area.
