I have the tapes that the LA guys put out as well as ones from Rhon Mizrachi from NY. IMO, I think both do a very good job of breaking down the material. The LA tapes seem to have a bit more flash to them, but that is not to take anything away from the others.
Both give a few different angles, with and without a partner. The LA tapes cover weapons while the NY ones are empty hand only. There is a ref. made by Rhon that this is something he would cover in future tapes, but I've yet to see anymore from him.
There are of course, other tapes out there covering off-shoots of KM. The most I've seen of those, have been short online clips.
