So many wonderful ships and only one to pick? I've had some tough decisions in my life but I think this one has dwarfed them all. That said, I choose the Crugarians since I use a repainted version of those for the Spelunker Race in my Miners Guild Mod.
AT, just so you know, I think you are a wee bit cruel making us choose just one

lol (I'm feeling a wee bit cruel too, I should have said I like your 'Next' shipset the best.)
Muahahahahaha
Cheers!
