I have attended a weekend Seminar with Michael Daishiro this year.
It was like most high quality Aikido-seminars, I have attended yet, but not as extraordinary like Saotome Sensei. - Well half an hour meditation was somewhat challenging. We did not do it that intensive in our dojo.
Added by some Daito Ryu and Itto Ryu Kenjutsu, which is somewhat different to aiki-ken. But aiki-ken knows several variations anyhow.
So you could have chosen worse. But it is not me to giver quality order to Aikido organisations. Just have much fun
