Yes, Kai's handbook is a great resource, although he hasn't updated in ages (and he knows a whole tonnnnnn more now, LOL). Although it was written quite some time ago, for those who don't know, Kai is now the associate sound designer to Tony Meola, one of the top designers on Broadway. He's worked with Tony on
Wicked and
A Christmas Carol at Radio City Music
Hall, among many, many others.
Not to mention that, on the few brief encounters I've had with him, he's seemed a pretty cool dude.
