Does it matter if I can name them? Does it alter the facts? Ok then, what about Igor Vovchanchyn (Russia).
And that is it, I train kung fu and not wrestling.
You can crosstrain all you want, but the fact is, if you dedicate 20 years to a dozen(and sometimes irrelevant) marial arts and if you happen to be in a situation where you are facing another man in the street who has dedicated his 20 years learning an authentic "in your face" style of kung fu- in an authentic kwoon, using the authentic conditioning including Iron Palm, Iron Shirt together with hard and soft chi kung - and has mastered that one art in all its aspects.
Then suddenly it kicks off then you have a good chance of having that "cross-training smile" wiped off your face in seconds. THAT IS A FACT!
That is why these arts are still around without them having been major global sports events, sponsored by big money and etc. If trained properly, they do what they are supposed to do. Very efficiently and very visciously.
Having said that I am not at all implying that your chances of winning against that same person would not have been considerably higher in the sports arena.
