Kosho Ryu is da bomb. The one thing I like about Kosho Ryu is that is borrows a lot of techniques from jujitsu. I'm actually looking at a school in the Northern Nevada area to study at. Great school and the instructor also teaches Danzan Ryu Jujitsu. Anyway, good luck on your journey. Oh, and skip most of the KM schools if you live in the U.S. Most are McDojo's. There are only two or three that I rate as legit. One is a school run by two Israeli guys. The main guy is Roy Elgayan and he distanced himself from the American KM Assn established by Darren Levine because he saw that what others were learning was significantly lower then what he was teaching. Look him up on youtube. He also teaches Hisardut, which is also known as Israeli Jiujitsu. Look hard and you will only find about four schools in the U.S. where you can learn Hisardut.
My recommendation is to stay far away from the American KM schools. The Israel KM association has a number of schools in the U.S. but a lot of them are McDojos too. Just do your research if you choose to go with KM. It's safer to study Kosho Ryu Kenpo because there aren't many schools that teach the Mitose style of Kenpo in the U.S. And remember, it was Kosho Ryu, as taught by James Mitose, that would the base foundation for Kajukenbo.
