My favorite ships are the Pathfinder class (USS Miranda B)
Excalibur class (USS Voyager A)
Hyperion class (USS Atlantis A)
Jupiter class (USS Montana A)
all Patrick Weber Creations, So bad luck Bolian Admiral.
Excalibur-class isn't actually one of Pat's - it's an old SFM mesh, though I can't remember the exact credits.
The Hyperion-class was originally for the Arizona-A; The Pathfinder-class Miranda was of course the title ship of the sim, but so was the Jupiter-class - that class was originally created for the Miranda-A.
Incidentally, the Miranda originally was a Kelvin-class ship - think a Soyuz-esque Sovereign. Pat had a habit of blowing ships up when he got bored with them. Even the Miranda-B got pretty badly beaten down once so that he could redesign her.
