I'm planning on starting a new campaign with some players who are new to Imperial Assault. I've been playing for a couple years, and one other player who will be joining has also. So there will be 2 experienced players and 2 new players. I will be playing the Imperials (possibly having joint command with one of the new players) and the rest will play the Rebels.
It needs to be a mini-campaign, because we only have a few months to do it before we won't all be available, and we can't meet frequently enough to do a full campaign in that time. So which mini-campaign would you recommend? Bespin seems really hard for the Rebels, but Twin Shadows came out earlier and I feel like they've improved their balance and campaign quality over time. So I don't know which one to do.
