Well now and days everyone is mixing up there arts...what about mixing in Snake or White crane with the wing chun. So in the midst of a fight you can change styles totally an through your opponent off especially if your sparring.
Just Wing Chun is enough to off balance any attacker's strategy... they don't know Wing Chun!
Snake style, as I studied it, has nice footwork, explosive and pushing in, good Chi Na and springy forms. For fighting, they trained San Da.
I believe it would not necessarily be a good time investment, except if the intructor has a lot of knowledge in Chin Na and Shuai Jiao aspects. And they are not that many.
