Grandmaster Wong Shun Leung is the real deal...he got the street fighter build and good Gung Fu...now put some knives in the Wing Chun players hands...three years you'd create a killer...one year of sil lim tao sensitivity building, one year of chum kil and bil jee and dummy work...third year get him on the blades and dragon pole...let him play with these weapons from day one...the fourth year he'd be ready for the revolution.
As a fighting style vs muay thai hand to hand in a cage...i'm betting on the thai dude.
Wing Chun is a refined method of Southern Gung Fu, imo you need the full Gung of the south all the big frame methods famous in hung ga and clf...tiger, dragon leopard. you need to develop the muscles and tendons, do some lohan iron body training and then you learn the crane/snake hands of wing chun.
that's how bhudda woulda planned it anyway, lol
