I like Tsui Sheung-Tin’s book, since it covers pretty much everything, but the line drawings, while okay for the sets, get a little abstract for the concepts. His ideas on geometry, while a little different from the mainstream, perhaps, are intriguing to say the least.
The Pan Nam series is interesting mostly because it covers some previously uncovered material on the Pan Nam system, and diverts in the end into the Chan Yiu-Min system as well.
Leung Gang-Moon’s book is the same. Not ideal in pictures, but interesting to see Yiu Kai’s line in book form.
The various pulp novels by Ngaw Hai Faatshan Yan, Ngaw Hai Saan Yan, while not historically acurate, give a lot of flavor to the old stories and characters.
Leung Ting’s Wing Tsun and Roots and Branches, while polical to the point of being distraction, are also very thorough in terms of pictures.
Augustine Fong’s series, and the very similar series from Randy Williams, were also very thorough and interesting reads.
David Peterson’s book is a very nice change of pace from the usual by-the-numbers approach, giving an invaluable glimpse into Wong Shun-Leung sifu’s thinking.
Every book has its good points and bad points, its parts that make you exhault and its parts that make you wince. If they come from your lineage, they can be helpful guides or study-aides, if from a different lineage, they can give perspective (either on other ways of doing things, or as Joy so aptly said, not doing them, as the case may be).
