If your ships are mostly ineffective, perhaps fighters and drones would be better suited to dealing with the Cue Cappa. Last I checked, fighters are immune to allegience subverters and computer virii. Don't know about drones, but they should work.
Of course, then you have to worry about point defense, but combine the fighters with high level missiles, and you should notice much improved success against those psionic bastards.
