My bad, I emptied my inbox.
As far as I know, sparring in Wing Chun is no big deal. Just use your common sense and avoid eye pokes and groin strikes, and there you go. Certainly many reputable WC sifus agree with me on that (Emin Boztepe, Kevin Chan, Benny Meng).
Did you read that thread? I had lots of trouble making my WC techniques work at the MT gym - not because the techniques themselves were actually bad, but because
1) I had done no sparring at my WC class and didnĀ“t know how to use them properly because of that, and
2) I had not learned many essential techniques at my WC class, such as jabs, hooks, crosses and roundkicks, so I didnĀ“t know how to supplement my WC techniques with those moves, nor did I know how to counter them.
I donĀ“t believe WC is amazing, nor do I believe MT is amazing. I believe it CAN be a good system, but many instructors insist on keeping their heads deeply buried in the sand about many technical aspects of combat, and they also ignore many essential aspects of training, such as sparring and physical conditioning.
