Textbook/Book Recommendation: Commercial and CFI?

[ArnoldPalmer]

As I get closer to completing the commercial and CFI rides, I was wondering if anyone had recommendations on some good books to really drive home and take the theoretical knowledge to a next level?

My usual game plan has been to knock out the written using the Gleim/ASA books and watch as many videos as I can. Then of course fly and get that stuff out of the way.

What book(s) do you recommend?

For CFI, all of them. Especially those listed as references in the ACS/PTS.
