That setup is excellent. I prefer to use the cheaper Wasp disruptors myself and sell the looted Hornet ammo, though.

There are two other gun loadouts that have merit. You could swap one of the class 5 guns for a Borroco shield killer (Corsairs) and map the caps lock key to toggle the Borroco on and off. This way you can beat down the enemy shields much faster and using less energy than with hull guns alone, and so there is more juice left for destroying the hull armour. Or - if you don't like the Borroco - swap the Outcast guns for the Xenos Tarantula/Adv. Tarantula. These guns have the same stats as the Outcast particle guns but they have 550/700 range/speed instead of 600/600. The higher speed makes much more difference in combat than the slightly reduced range.
