One of the builds posted on page 1 is probably the best one.
Patrol Leader + Rebel Captive
Bounty Hunter
Omicron + Darth Vader
I'd say for any low PS big ship build, Rebel Captive is almost necessary to beat Phantoms, and Vader is pretty important to beat Interceptors. Other squads would rely on you outplaying the opponent and using that bulk to clog the board and survive lots of incoming fire.
That being said, you could run...
Patrol Leader + Tactician
Bounty Hunter + Tactician
Omicron + Tactician
That'd be a cool squad. Patrol leader doesn't get the MOST use out of Tactician, but you'd have a blast trying. Maybe could put in Oicunn instead.
Overall, though, I think I'll give that archetype a try.
