Dale,
I got some footage of Master J. Chung Li from an instructor in Denmark. Master Chung Li did have some amazing skill. That level of LHBF form is truly something to aspire towards.
Unfortunaltely I am not going to the festival either as Shifu Dillon is having a seminar in August and I was told by my Wife to choose one or the other. Since my main interest and point of study these days is Liu He ba fa, my choice was Shifu Dillon. If you ever have a chance to get Mark Mcgee's editorial of Master John Chung Li's commentaries on the "Chinese Five Word Song", is is definately worth the read. I feel that Shifu Dillon's "Five Character Secrets" truly compliments Master Li's comments and gives many meditations to work with.
It is interesting because I was first studying LHBF under the guidance of Shrfu Mike Patterson, but when I came across Shifu Dillon I practically stopped all other studies so as to be able to devote as much time as possible to LHBF. It seems this is what I was looking for. I hope you find it in Bagua or wherever your journey takes you. I am pretty far from where I originally thought I was going and have totally re-evaluated many things in my life.
All the best,
Ian
