Nice topic. Good to remind people that wing chun is an effective art and one worth doing
I have trained in martial arts for almost three decades and it is one of the better styles I have learnt
You can get bad schools within styles - I have been to terrible BJJ, karate, TKD, CKD, Escrima and MT schools/gyms/dojos, but I would not judge their arts by that. People tend to whinge about wing chun because it doesnt have much link to the cage. It is a ridiculous argument - the cage is nothing like the street. You have gloves on, mouthguards in, a set of rules you must follow, an octagon you must stay in, and you know the person you are fighting. It is still a tough envronment and most of the cage fighters could easily handle street confrontations, but it is not really streetfighting
I use wing chun with other styles but there are some extremely good 'pure' practitioners who could use just their chun to take people apart
A great testimony to how good wing chun is, is by the following link

This is how may black belts have come to Kamon (there were more, but some dont want to be on the website)
