[Corsair]

Depends when and what type of career I am after.
Early war Wilhelmshaven, although Kiel is a nice place as well. In France Brest if I want a VII career around the UK, Lorient for IX type long patrols. (may be also because this is the region where I was born and I know the places irl)
In the Med Toulon as I know it as well...
