Always nice to hear from you and read your posts.
Just an FYI regarding the your comment about the Yang Zhenji Tai Chi Dao video

This is basically the form that we do; although it is interesting to see the small differences.
I’ve seen and have been taught several small differences that I’ve seen in older Yang Family students Dao forms. At the 0:43 – 0:48 mark in the Yang Zhenji Tai chi Dao video you are referring to, I’ve seen this move done by Tungs, and by Fu Zhongwen’s son and others.
On another note, here's a video of Tung Hu ling performing Tung Family Fast Form.
