Hey Mas Judt- you're right- I have a limited understanding of CMA and any kind of bag training that is not western boxing or Okinawan makiwara. And I appreciate your careful word choice and your stating that you don't mean to offend. That's classy and by now I presume you and the other guys on this thread are cool like that. So thanks and remember I don't intend to offend any of you, either.
My only exposure to Chinese arts was for that short time that I explained, and as explained it was not typical or traditional. Only in recent years did I learn Taiji from a well-known Wushu master and I continue private lessons when time permits.
