Hmm good topic.
I have owned the vette since it was launched, i used to run 2 adv plasma(in class 4 slot), 3 cannons, 2 beams- old skool build, now with engineers totally different.
I would say, depending upon if you are running solo bounty hunting or winged up, this can vastly change your load out, as one can run thermal, and the other kinetic.
My usual wingman has a MC build for his vette, while mine is a odd ball build.
2x class 4 Eff beams
2x class 2 cannons, Overcharge with high yield & know off course(brain freeze atm)
2x class 1 Eff beams, healing
1 class 3 Pacifier cannon, double shot with caustic.
All the usually mods charge enhanced power distributor, oc lvl 3 power plant, dirty drive 5, wide scan 1 sensors, grade 3 fast scan KWS(class A, 3k range).
Class 6 fighter bay, twin plasma condor, twin bean taipan- elite co pilot.
The beams are great, for beating stuff down, the class ones, i just use for assist targeting or to heal as needed, procs should change, but, meh i am lazy, as i prefer a close up fight, so they are handy.
Cannons are great for punching out modules.
Pacifier frag cannon- O M F G- the stats do not do this gun justice, it is a beast of a gun, i think the one i use has about 348 dps! It is great for shredding shields or just annihilating the target, i prefer to use it for larger ships as it is fixed(3k range, so much better than a standard frag). The class 4 beam have a trigger time of about 35 secs with both of the class 1 beams also running, so, yea the efficient beams work wonders.
Heat wise, in a prolonged battle, probably maxes out at maybe 65% heat, so no issues at all.
I also run a class 7 bioweave for BH(thermal), or a Prismatic for CZ(heavy duty too) as the bioweave recharge rate is insane, but the prismatic- i could go out for a evening and come back to watch it recharge...so i also have 2 scb- specialised.
But whatever you run, make sure if "feels right", nothing like spending hours rolling weapons, just to discover- man they suck :/
Fly safe and pew pew on!
