I just realized how far from the original question this thread has gotten LOL.
It started with me asking, "If we take it as an indisputable fact that wing chun has no outside game, and learning another art is necessary to fill that gap, then what long-range (by that I mean KICKING) style would be a good match with it?"
That question was never answered, although it WAS briefly addressed when someone asked why I thought tae kwon do was out.
I answered it.
