Site Searching: What do you use?

[Turin]

I always try to get a province site searched by at least lvl 2 mages using indi and national mages.
After that I use the searching spells on those provinces who still have a good chance of having sites.(for example mountains/swamps where my mages found only 0-1 sites.)

An exception are underwater provinces, those always get the voice of tiamat + haruspex treatment, without having mages search first. And provinces with odd scales and/or unrest get searched remotely too.
