How does the range compare to cannons and torpedoes?
I use 4 rails (2 med 2 small) on my asp all the time. So satisfying when you get the timing down (they charge and fire at different speeds) so you get a Ba-boom and whip a ships shields down in one hit.
Range is about the same but they're instant hit so you don't need to worry about them reaching their target and your target moving at the last minute.
Great for drives and subsystems but high skill ceiling. I personally think the ammo could come up a bit and I'd love to see large ones but they aren't your everyday weapons. I wouldn't use them for cz or res but for pirating they're perfect if expensive ammo wise.
