Just wanted to point out an issue with the 60 BT March thingee...
I started a game as Mantua and, as mentioned, made a march out of Papal States. I gave them enough provinces to keep them below 60BT but keep them fairly wealthy. (of course, the main reason to march Papal States is to keep good catholic relations, prevent everyone from hating me and prevent them from popping up elsewhere).
However, they were useless. I think their force limit went from 17 to 21. Giving 4k more troops to my ally is fine but not worth the poor relations and receiving no income.
To make "marching" even more pointless, for around 20 years I had them as a march they never fielded an army larger than 14k troops.
After this failed experiment, I suffered the -200 relations to convert them back to a vassal and I'm even more at a loss of what the point of marches are, as this was the single scenario where I would have found them useful.
