[BTS] How to use trade bait?

[Fish Man]

Hey, I'm thinking of moving up to deity, and I was just wanting to ask - what techs would you generally research as trade bait? I know aesthetics is one, but what are some others?

Drama & Music, compass, sometimes CoL (needed for CS or Pyras setting), Paper & Philo with the Lib way always trade well (very popular for Cuirs).
Ofc nothing wrong with getting currency yourself often

Ah, thanks. I was wondering why in the world anybody would tech aesthetics in those LPs as opposed to something more useful, but now I understand it's like getting multiple techs in one if you trade it away for IW, math, monarchy, etc.
