I gotta be honest, I always think when I hear about Catch instructors like Furey and Cecchine(and I love Cecchine's instructionals, even if he does abuse his partners horribly), that it stands to reason that someone wanting the best catch-as-catch-can would go to guys like Gene Lebelle, Frank Shamrock, Ken Shamrock, Eric Paulson or if you can somehow make it to Japan, Sakuraba, Funaki, etc. It seems to me that the catch-as-catch-can employed by such guys is comparable to say, shotokan karate and kyokushuin(sp), in that one is tested in competition and evolved and changed as necessary(and of course, unchanged where unnecessary), whereas the other risks becoming anachronistic due to its lack of testing through competition.
I also wonder why Furey and Cecchine never seem to really claim the aforementioned guys and vice-versa. Forgive me if this last comment sounds naive(as of course, the obvious answer is that acknowledging other experts detracts from marketing in the case of Furey and Cecchine). But I wonder if there is something more to it than money...perhaps people feel that the catch-as-catch-can descendants who compete in the MMA world don't utilize "pure" or "true" catch-as-catch-can?
