Do you have a progressive mind set?

[T.D.O]

Oh, the 3 lines reminds me of learning about multi-attacker applications in animals forms. Well constructed forms should handle 3 attackers covering all 360 degrees around you...

Know of any where I can read of such things?

Wing Chuns forms don't focus on scenarios or applications. More of a Dao yin.. in my opinion, with the focus on musculoskeletal structure, I think acrobats had an influence in it... Funnily I've seen (on this site) someone with more knowledge than me saying the same.

The only form that even considers the opponents centre line is the dummy form, which I don't know..
