Roman empire in XVII century

[attyla]

I have a little problem with choice of german states in XVII century. I'm sure i should make electorate of Brandenburg, Saxon electorate, Bavarian electorate and roman empire. I think about one more german state but i don't know which one. Maybe Mecklenburg electorate or Duchy of Brunswick? I really don't know. What do you thing about it?

And second thing: I cant link states and proper religion. If i'm not wrong, Roman empire, Bavary and Saxony was catholic and Brandenburgy was lutheran. Am i right? And what about Meklemburgy and Brunswick?

I'll be grateful for some information about this matter.
