Huh. Never considered experimental weapons for that slot... Are Shock Cannon any good? Heard it overcooks your ship when firing quickly and has very low ammo.
After trying them out, I found they lasted about as long as the cannons I had, but did more reliable damage. Synthesis of ammunition requires manufactured materials, so that's expensive. And in my corvette it did not cook me. Probably because I only used it in short bursts together with the small frags. I can handle all my weapons on a single pip. Shock cannons seem to work well enough so far.
