Yeah I do well but am primarily a tournament player. I have a bunch of recommendations on good tourney books. For cash I'd recommend anything by Slansky, starting with the theory of poker. It's dated but still fundamentally sound.
I will say I have found nothing better than posting hand histories and having discussions on 2+2. Actual real "what would you do with this hand" examples, and then listening to what good players have to say, is hard to beat.
