It is refreshing to meet someone with your obvious exposure. I started training under Stephen Hayes (not recommended, honestly- if anyone wants to talk about it, please e-mail me), then trained under Shawn Havens (highest recommendation), who is now with the Jinenkan. I currently train under Bud Malstrom at the Bujinkan Atlanta Dojo.
I was not attempting to say that the "X-kans" do not have kata, merely that our kata use real bodies. The sole exception I know is the Sanshin no Kata, which is generally used as a warmup...
