Probably my Phoenix will be my "home base" as it will be the luxuriously appointed. With that said, I also see myself spending inordinate amounts of time on my Banu MM, or Crucible, or Endeavor, depending on what I'm focusing on in-game.
Possibly house wiring, possibly North Carolina. Spring thunderstorms can be absolutely beastly there. Also the summer ones. The autumn thunderstorms can be pretty bad too, when they're not overshadowed by the hurricanes.
The 325a is solid little ship. It's a decent dogfighter, it can carry a bit of cargo, and it's fairly quick. Definitely a step above the starter ships, but it gets outclassed by other more focused ships.
