Are the SMR kata you practice all from a standing position?
Yes, all standing
Are the Omori Ryu kata all from kneeling save Koranto?
Yup.
Are the Seita Gata kata 10 or 12?
Fairly certain it's 12, I'll double check next time I'm in class.
The fourth set we have in MSR is kata from Keshi Ryu as well as the Chuden and Okuden levels in Omori Ryu.
Crap, I was just in class tonight and forgot to look on the wall and take note of what the fourth set of kata's we do are... I'll check on Thursday assuming I don't forget again lol We have a training manual for the kenpo curriculum, but unfortunately the names of the iaido katas aren't in that or I could just look it up in our manual.
