Daido Juku looks sweet, its a European offshoot of the Kyokushinkai which split back in 1981, which has its training geared STRICTLY towards kumite and from what I have heard from friends accepts only advanced or serious players.
Using helmets, they allow headbuts, groin kicks and groin strikes, throws, tackles, elbows, knees, stand up grappling, limited time ground fighting with chokes and joint locks, submission fighting, the only rule I see is no g and p, but the punches from the mount can be simulated for points.
Interesting indeed and nice to see.
