I think it's decent so far - some of terminology is different than what I'm used to (possibly a result of it being from 2010 or so) and there's some typos, but I'm finding it very readable.

(There's an archived version of the forum thread it was originally posted on here. I can share the ebook version that used to be hosted on Wuxia Society (they seem to be redoing their website), if anyone's interested in it being added to the resource folder).
