Not for its impossibly huge size.
In the beginning go dual subachs + all tempests
When the Harpoon becomes available, I switch one bank for harpoons. They're good for nailing SF Dragons and SF Manticores that I can never hit with primaries.
When the Kayser becomes available, I use that on all craft, except the GTF Erinyes. For that I just go 8 Subachs.
When the Trebuchet becomes available, the the Harpoon bank is swapped to Trebs.
Tempests are always in unless I have bombs, due to their superb ability to grab capital ship kills for me.
The only missions I really use the Maxim in are Their Finest Hour and the one where the Sathanas first appears (the Fog of War?).
Because shooting up a stream of Shivan cruisers is immensely satisfying, and because the Serapis is too flimsy to actually do anything in other than park 2km away from a gas miner and start filling it full of maxims. Makes their explosions non-isssues
Never touched the Circe nor the Lamprey. If it doesn't make things go BOOM, I don't use it. I can't micromanage my weapons well enough to blast off the shields then switch to maxims.
