regarding a 'second pocket' version: You absolutely have to check out Bradford Hatcher (https://hermetica.info/).
He is actually the biggest inspiration behind my development process. His work is incredibly deep, pragmatic, and distinct from the 'Christianized' tone you sometimes get with Wilhelm. He offers his massive 2-volume translation for free on his site.
I am actually considering digitizing his text as an alternative option on my site because his word-by-word matrix is just mind-blowing. Let me know if you find his style fits your 'field reading' vibe.
