Hisardut any good?
What do you guys think of Hisardut or Dennis Survival Jujitsu? Here are some clips of it. Dr Hannover has a tenth dan in Jujitsu and a 3rd dan in Kyokushin Karate under Mas Oyama. As well as a 5th dan in Karate under the Isreali Karate Federation. Hisardut mixes Kyokushin Karate, Judo, Jujitsu and other arts
That guy has really good kicks for an old man!
Outside of that it is hard to say really. The first video was some very non-alive technique training but... that's probably the kind of thing that works best for a news camera.
The 4th video had some interesting sparring that looked like a mix of kyokushin and Judo but they never completed their throws. Maybe in training they do? Or maybe they never do? Impossible to say. Would make for some pretty good sparring if they do.
I'm also not a huge fan of the lack of head punching in Kyokushin, but then again plenty of people have to get up and go to work in the morning without a busted up face so it's not a completely unreasonable way to train.
