Weapons: Missiles. Missiles everywhere.
Modules: Put Makeshift Shield Generator and Extended Shields on each. Now they will automatically raise a shell of shields that cover everything, under the player-controlled main shield.
Strip the center for maximum OP, put back ECCM Package (the built in missile is incredible), and use Hardened/Accelerated Shields and the mod that gives +25% vent rate. Then put remaining OP into vents.
In battle, you're invincible: You can tank shots on the shields until your flux is halfway or so, then quickly vent, and the 2nd layer of shields on your modules can take the hits long enough for you to finish venting and raise the main shield again.
Meanwhile they're wrecking everything close with massed fire, and everything at medium and long range has five cruisers' worth of missiles chasing it down.
