I started this thread from the "On why I think Hendrik is on to something." thread in order to get away from bashing one another and get back to some real productive discussion on training aspects of the wck system. If I was Gene Ching, I would have two separate wing chun sub forums. One on wck politics and wck agendas and the other one on productive wck training aspects discussion.
I agree! Both sparring and chi sao develop different attributes which contributes to overall self defense training. The main goals of Wing chun sparring should should focus on developing awareness of controlling distance and timing. While the main goals of chi sao should focus on controlling and disrupting the opponent's center of balance.
In regards to long and medium range sparring, I believe after years of investigation in various kung fu systems, western fencing and boxing Bruce Lee came to this conclusion as well. So we don't have to re invent the wheel, he has already done the ground work for us. Wing chun sparring doesn't have to look like kickboxing if you know how to use your footwork with angling with proper awareness of timing and distancing.
