Thanks for the replies. I have practiced SFQ I only to some extent. It was always difficult to decide which style to pursue. I tended to stick to my methods.

Let me present the question in another way. If I change my QiGong routine to SFQ I standard methods. Would that practice be compatible with Dao-In, and could I still practice Tai Chi? Or would the energetics be in someway in conflict?

I think going to the retreats would be great. I've always wanted to do that - just a matter of finding a date that works with my work schedule and life responsibilities.
