Hi
My advice? ditch gimbled all together. Use fixed beams, more powerfull and more involving then gimbled.
As for kinetic weapons, if you want to equip kinetic wpns, i would go 1 laser 1 gun. Kintetic wpns don't do well vs. shields and cost money to rearm. Cannon shells are 40cr a shot, I'm not sure how much MC shells cost.
Fixed MC's can track targets as long as you aim your fire via the sight reticule. Fixed wpns out perform gimbled wpns considerably (30% in beams IIRC).
Experiment, if you don't like a wpn, sell it and get a new one. YOU DO NOT LOOSE CREDITS ON SOLD WEAPONS.
Rinse & Repeat.
Happy hunting.
