I usually have escorts with fighter bays. Try using a UE Cruiser, with an Azdara bay, and have 2 Azdgari Warships, 2 Zidaras, 1 UE Cruiser, and 1 Igadzra as an escort. With any luck, by the time the Disco Bison has killed all your fighters, the capital ships will have done it some serious damage. And because the computer treats Zidaras as fighters, and the phase beams are really good, I can usually defeat it with little trouble.

I want a doughnut. A doughnut as doughnutty as a doughnut made of flour, water, one large egg, sugar, a pinch of yeast, cinnamon to taste, and jam or jelly filling, depending on preference. Its not a doughnut as something in any way metaphorical. Just a doughnut.
