Archangel,
I know of the Seidokaikian (kyokushin offshot) founded by Kazuyoshi Ishii (aka Mr. K1 himself) but I don't know Andy Hug. I do highly recommend Ishii's book "Katsu Tame no Karate" (Winning Karate) it is a good book on kumite.
Naf and others,
Blumming is well know as a good man in Kyokushin circles. However alot of so called "truth" came out AFTER Oyama died. Pple flocked left and right to tell the TRUE story of Oyama, each with their own twist. (Blumming mentions that Oyama knew nothing of throw, ne waza, etc BUT in several of his books <Japanese version the english ones have much taken out of it> it shows nage waza and ne waza see what I mean) I take all legends with a grain of salt. From MY experience I have found Kyokushin a VERY good form of karate. I have become very FORMINABLE in th system, but then again I have dominate every system I under took. What I got from Oyama. He was a showman I will glady endorse that he LOVED to play up the GODHAND name he went by but he WAS TOUGH I don't think ANY karate man could stand up to him in his prime.As for the Bull thing, like I said he almost died fighting one in mexico, the reason I think he didn't fight many bulls in THEIR prime, I got confirmation for good sources tha Oyama was hospitalized there for a gore wound so if he NEVER fough bulls out of Japan where did the wound come form?????? Take every thing with a grain of salt.
