[Alneyan]

I have always been partial to a Mara myself, with the standard double Kaysers (energy has never been much of a problem though, as few targets take more than a few hits to go down): jolly fun! And that Mara mission gives so many nice vessels to take down, all for yourself...

Still, my favourite will be the Great Hunt (I think) in FS1, where you try to catch up with You Know What. The mission can be downright easy (run like the coward you are!), or you can have some fun taking down everything on your way (destroyer included, of course), and without losing a single ship in your escort. Dofighting madness! (And hope the friendly bombers can deliver the goods...)
