Battle Brothers Hits Early Access

Need anyone’s help for my indecisiveness LOL :)

Noble War just commenced and I have excellent relations with House Horn, but they only have 5 locations (2 large plus 1 citadel).
House Rabenholt is stuck between the two rivals. It only has 4 tiny villages (just 1 citadel).
House Folsach is a monster and takes up the entire SE. They have 8 locations (2 large plus 1 Citadel).

Which (if any) War Ambition should take at this stage as I want to maximize gear farming from this war? Also I found two magic weapons and was wondering if I should buy them. They’re $10,000 apiece. A two-handed hammer and 1 handed flail. I have $30,000. I don’t have a 2 handed hammer yet, and one of my guys is a brute flailer so they seem like perfect weapons for my group… but then I’ll be in tighter money situation for noble war ($12,000 left over which may be plenty?) I still need a decent archer. Mine stink and can’t hit the broad side of a barn and I’m getting flailed in archer duels with decent opponents.

Thanks! :)
