As I so often am reluctant to admit, but will, I have only read about 80 pages of DR (but I did read the infidelity section long ago). I did read all of DB. Many people say that DR is the better of the two and since it's written after DB, and contains the same basic principals, I would probably agree. Having not read all of both, I cannot comment on it fully.
As for giving a copy to your C, I don't see any problem with it, I just didn't do it in my case. Dunno why really.
