No, just don't want to come across like I represent complete knowledge of WC of my Sifu like the majority of yahoos on this forum. The lineage wars started that way, why would I want to perpetuate it? IMO everyone is their own version of WC. The Sifu just guides you while it's up to you to understand it both objectively and subjectively. Why would I talk for him when I'm not him?
Stupid joke coming from the Grammar Nazi in me - your vs. you're.
It failed. *sigh!*
But the questions about the "leakage attacks" still stands.
I have often seen Fong Sifu get very quick shots in during chi sao, where he'll strike very quickly and then go back to the position he was previously holding. (over and over again in the first 20 seconds or so of this video: http://www.fongswingchun.com/FlowingChiSao2.mp4 )
I wonder if that's what it refers to?
And "invisible center line"?
