If I research currency I can go code of laws afterwards... thinking about doing that now that the Oracle has gone. I want aesthetics for the Parthenon at some point though (I'll need polytheism as well for that).
Aes -> Curr -> CoL -> Myst -> Poly -> Constr ?
Then finish Sury off. I, personally, would research Construction right after Aesthetics, but I'm a hot blooded warmonger. Granted, your argument against using Spies is true, so that would probably be unfeasible.
