Hi Natitude,
As mentioned in your other thread, there are some things that can be said about "Kindai Ryu Jujitsu"… and, honestly, it's a mixed bag. Kindai Ryu was founded by Charles Neal, who was one of the early Judo pioneers in the US… as well as being a karate-ka (Shito Ryu, from memory). And, realistically, it's kind of a mixture of the two, which isn't too bad. However there are some gigantic questions over the claimed history, as well as some prevalent and very basic errors when it comes to their own terminology and so forth, which always puts me on the back foot when they arise. This includes issues as simple as not correctly translating their own name, to more fanciful ideas like claiming that their system is "the most dangerous Japanese art ever forgotten"… which is coupled with the idea that the Japanese buried the art in order to not let it fall into the hands of foreigners… honestly, that's all a bit Hong Kong Chop-soky movie fantasy for me… and, with that, I'd put them out the window straight away.
What I will say positively for them is that, despite the bizarre claims, the core seems to be relatively solid… and of much better basis than many of the other systems of the same era and pedigree (Ron Duncan was originally a student there, for instance… hmm…).
