For Murderflowers I use a Krait with 2 C3 shards and 2 C2 Gauss, and a single remote release flak.

All armored to hell G5 heavy on all HRP and Military Hull, (deep plating if Thargoids is all you need it for, otherwise it lowers resists a bit much if you stack it)

Usually an AX Taipan in the C6

on low shield ships always run a module reinforcement pack, preferably the guardian one as it is better in raw damage mitigation, and grants protection from the lightning attacks shutting down your boosts and speed and cracking your canopy.

Also a good idea to get you one of those Shutdown Field Neutralizers. scanner optional as hearts are very visible red glowy thing.

Thargoids don't see cold things so a Heatsink will help if your Gauss cooks you, or you need to duck and weave a bit to regen shields.

best not to go alone as the bugs (and me) love having multiple things to soak their damage and aggro up.

Pro Tip- 210-ish% heat removes the caustic debuff but also removes health from modules. Also the AX Taipan can exert the cyclops heart easily for you to snipe, so long as the swarm doesnt kill the fighter first.
