Every body knows that AikiKen and Jo are just learning tools and could not possibly equal in efficiency and sophistication other specialized Japanese arts.
Tachidori and Jodori are a different story as I believe they are pure Aikido essence.
Whether Saito Sensei learned or adapted his Aikiken and Jo from Osensei or not is irrelevant, as these have been adopted and taught everywhere regardless of the style.
I have one request from the Iwama guys. There is no need to distribute accusations in a hostile way against Aikikai especially that I believe that your phobia is unfounded. I usually love to practice at Iwama-ryu dojos, but I am put off because I have to listen every time to lectures about who has the real Osensei Aikido, the Late Doshu or Saito Sensei.
