Developing Good B vs. N Evaluation Judgment

Hi, All! 

I am looking for resources on developing a good sense of how to evaluate (and use) B-N imbalances.  I have a good sense of the basics (e.g., minor pieces, not rooks, halt and unhalt passed pawns), and I have gone through a number of non-specialty books on this topic.  Are there any decent resources on evaluation (and use) of minor piece material imbalances?  I have seen only three real options: "Mastering the Bishop Pair" by Borulia, "Bishop versus Knight: the Verdict" by Mayer, and Averbakh's on Bishop-Knight endings.  Are there any others?

I am looking for books and other resources that discuss one of the following three things, mostly:

1) Evaluating whether one side's N is better than the other's B.

2) Determing whether to create a material imbalance because an evaluation of some sort says you should (such as in opening principles and middle games).

3) Complex evaluations and uses, such as BB vs NN, BB vs BN, etc.

(note: I am guess minor piece endgame books are abundant, but I have not looked.)

I've heard good things about the Mayer book, but have never read it myself.

The (in)famous Silman has a lot of examples on this topic in his Reassess your Chess book.

Thanks for the input.  The Mayer book is fairly expensive on Amazon, and I think it is out of print, unfortunately.
