Some possible additions. : )
Very nice group in Reddit here:
https://www.reddit.com/r/Sixlinesdivination/There are some more books as well, I mentioned them in there in the same topic. But in general one is:
The Authentic I Ching - Dr. Wang Yang and Jon Sandifer
He tried to use all 3 systems together. Some parts were very interesting, but in general wasn't really the best fit for me.
There are a lot more materials for Liu Yao and Health now. One example is this:
I Ching Acupuncture - The Balance Method by David Twicken
There are others, usually checking around Dr Tans material can lead to interesting results.
Some more youtube videos and websites around as well, but nothing different then what is known already for the most part.
There were few interesting articles in website, like why the branch assignments are what they are, going alittle beyond what we know(opposite direction for yin and yang branches on yang trigrams etc.) but can't find it now.
Some facebook I Ching group were mentioning WWG, apparently with the idea they plan to move toward more topics around it... Can't say I saw that actually happening, so irrelevant for here at this point.
