I also think that 4 x Kihraxz and Serrisu w/ Hull Upgrade (or was it shield?) would do well. Have Serrissu just turtle every turn and hang near the Kihraxz. Who does your opponent shoot at? The ships that cause damage or the ship that lets them evade damage? The number of shots to take out Serrisu should allow the Kihraxz to put the hurt on your opponent and let you pull through. Well....that's the theory.
4 Cartel Marauders + Serissu totals 100 points, so no room for anything else on Serissu. It would still be interesting to try.
Odd....OK. I could've sworn I counted it up before and had a few spare points. Oh, well! Faulty memory.
