Ok, I think I'll go with Ethereal Squirrels. The start locations are almost certainly better than what the AI would assign. The only risk is that it doesn't specify that all the start locations are land. So if one of the starts was a water start then the game would have to assign an additional land start location. Which probably still leaves us better off than we would be with the AI assigning all start locations.
Also, further up on the map list is another version of the map that specifies 7 land starts so I'm hoping this is an updated version of that map that just fixes some province connections.
