Fair enough

and thanks for thinking this TL deserves an update!
As to the update, I am not sure I see much long term prospects for the Della Scala, namely, I don't think I can have them realistically do nation-building in the part of Italy they would end up controlling, which was my initial idea. It could last for another generation maybe, but there will always be cadets/bastards/usurpers ready to find common cause with external polities or local rebels (Padua here is the main culprit, either I raze it to the ground - and lose my biggest city- or it will revolt, and call in Venice, as soon as I try to transform my collection of
signorie into something vaguely resembling a "centralized" state).
Also, there is the problem with Milano: to become hegemons in the Po valley the Scala have to beat Milan sooner or later. This could happen under the right set of circumstances, but then my Verona TL would basically become indistinguishable from a Milan TL and at that point, why not use someone like GG Visconti?
At the moment my interest has also swinged back to South Italy, I will probably try to do an Hohenstaufen TL as soon as I have a bit more spare time.
