I came to the build for similar usages, by toying around on the test servers. I've hit up the Federal Gunship with 4 such C2 torpedoes; then came the idea of the FdL. I see it's primary strength, however, even more precisely in the defence of sectors and areas. The FdL suffers low jump range but has great top speeds and high mobility. Combined with this loadout and perhaps combined with some more continual fighters, it should greatly help keep systems in check. I imagined this in case of Sothis. Pirates in Dropships, Clippers and the like could be blasted away within one salve, or heavily damaged if fire is spread some bit.
I am playing the loadout on the mainserver with a fixed C3 beam, however, as it saves some energy, gives more damage if the hits come somewhat constantly, and thus helps the largest problem of this: heat. If you're too low on weapon capacitors the energy will be taken from the power plant, what quickly can heat your ship well above 400%. Since I'm doing that, binary systems really only feel a bit more expensive than buying the fuel thanks to repair bills, but nowhere near to danger. The maximum heat damage my own torpedoes had caused me so far was 20% something directly away from hull. So managing those shield stripper weapons is a very important thing to do.
Also, 120k credits to reload 8 torpedoes. Doesn't matter too much if you hit something valuable with them, and as you're in a FdL, exclusivity should be part of one's lifestyle anyway, be it the ship itself or only taking the best munition.
Cruising around with that murder ship is the best feeling ever! Well, almost.
There's only one thing I don't know how to take yet. On the testservers it's already implemented that destroyed power plants won't destroy the ship anymore. So, nuking that won't cause a whole Conda to explode in the future. However, it does seem to immobilize them and limit their actions strongly. Also, the torpedoes will still take a whole ton of hull% away. I'm not sure how I'll feel having to clear the target after hitting all torpedoes. Should still happen rarely, hope. So far, even NPC Gunships are killed by a full volley, and they have very much armour as it is.
I love that loadout even more than I loved the C4 PA, as crazy it is to say.
