Put it on its own fire group and fire it sparingly, synth more ammo, or roll corrosive high cap magazine. Best options.
Yeah, I'll have to rearrange things somewhat when I get a chance, but there will be much hunting about for materials between now and then. For the time being it works well enough and I have synth mats for several reloads should I need it. My anaconda has reached a strange balance where it works quite well against a range of situations but is not meta max.
I have:
a pair of Large Turreted Pulses up top (emissive and scramble spectrum) which are extremely effective vs nimbler craft but obviously forgoes max alpha in exchange for useful effects. I forget the base mods on them but iirc it's a lightweight and a SRB (level 1s).
The bottom Large is a gimballed MC (OC5) Incendiary.
The Huge is also a gimballed MC (OC5) but with no special effect (very nice roll though).
The medium side hardpoints house a multicannon (OC5) Corrosive and a gimballed cannon (high cap level 3) dispersal field wish is quite useful for its effect and module sniping.
On the smalls I have both High Cap level 3. One is a feedback Cascade rail and the other a drag munitions seeker.
I also have resistant grade five shields (6a) supported by five ABoosters (mixed effects), a modded 7a SCB and a 6a SCB. A pair of heat sinks works well for timed dual release.
And a single chaff.
She's an odd ship, but she does the trick really well for me in a variety of circumstances... oh, yes also a pair of SLFs.
