Direct fire Stubby with SPC BC and armor breaking gemini turrets
The lifetime increase on SPC lets us forego T1 lifetime in favor of the mag mod. This ends up giving you just as much ammo as LWC would and you trade a bit of range for slightly stronger beams and double the magazine size.
Armor Breaking Gemini turrets have an ~87% chance to just straight up ignore light armor which on something you can’t manually aim is quite good.
