I too have been intrigued by the Chen Taiji phenomenon! There is a Kung Fu sifu who has studied rather extensively and appears to have a family certification on the wall from the Chen family. Unfortunately, he is about 2 hours away.
There is a acupunturist in my town who does the Chen forms in a public park, but he seems to be of the "lotus eater" crowd and maybe a journeyman teacher at best. I'm not too crazy about the public park kwoon approach either, although maybe it would be cool.
My Wing Chun sifu expresses concern(as does my Uechi sensei) about learning too much and getting at cross purposes in cross training. The moves in the Chen style of taiji have a different way of avoiding blows that is somewhat different(bowing the body, etc.)I expect this may be a reflex that can also generate power for a response.
What intrigues me is what I have heard and seen in demos so far, is the kind of power and energy confluence that is generated!
I would be interested in your thoughts on these matters.
Thanks in advance,
