Only in my lineageIs everything in wing chun, or is wing chun in everything?
Try telling that to one of the old time Choy Li Fut guys. I suggest only attempting it while you have him at gunpoint.
Re: Mario Sperry
He WON the first Australian UFC in Sydney, from a field including Elvis Sinosic and Chris Haseman. Submission by chin to the eye socket over Haseman IIRC (a tactic which Haseman also defeated Elvis with - the rules allowed it).
The quality of these events has improved exponentially since those days, which is not to disrespect the fighters mentioned.
Catch - it might be great, but you can't learn it in Oz (unless you buy Furey's tapes, I guess, which I have no plans to).
Most sensible highranking BJJ'ers here crosstrain in Greco or Freestyle Wrestling, and would almost certainly jump at the chance to pick up Sambo, Catch or anything else that came along. Those guys all crosstrain striking as well.
Sakuraba as a poster boy for catch probably has some validity, about the same as using Bruce Lee as a WC poster boy. Both moved on and expanded beyond the boundaries of these arts, as much as their "purist" followers might argue or wish it otherwise.
The sound of one hand clapping? Go to a mangrove swamp full of mosquitoes - you'll hear it soon enough.
