Re: Kata/Suburi apart from Saito Sensei
Imaizumi (Shin BUdo Kai in New York CIty) teaches a variety of weapons work, including Saito's.
If it is 'innovation' you are looking for he has developed 2 kata of his own. I believe they sell a weapons kata DVD at the dojo.
Tohei and the Ki Society have 2 unique Jo kata that they used to teach.
