Thank you kindly.

The Aikido dojo I attend has been teaching us several "well known" Jo kata, such as the 13 and the 31. However they are not the "accepting", "non-initiating", "unbalancing" martial art that I have come to associate with Aikido. Jodo seems way more wham-bam-spear-and-pound.

It seems every time we have a seminar and the visiting Sensei does "weapons" (bokken and Jo, usually) he has his own version of the Jo Kata with 31 moves. Is there an "official" version?
