Wait.... mag stabs give more damage then heatsinks? (850 is really pushing it, you are counting some very expensive implants i bet)
If you want to maximise dps, shield fit it and bring 4x heatsinks and TE's, tad light on tank but dps should compensate, also passive shield regen beats having your cap drained by an armor rep :)

My 3 HEATSINK Harby with Navy multi does almost 800 dps with heat and drones 850 might be possible with conflag as my skills are not perfect

Pulse Harbinger
Max Skills
3 Heatsinks
Conflagration
5 Hammerheads
= 848 DPS

Beam Harbinger (ew, gross)
"
"
Aurora/Gleam
5 Hammerheads
= 472 (Aurora) - 707 (Gleam) DPS

That's max skills for official reference, not necessarily practical purposes.

I get 798dps OH and im not perfect on skills

all level 5's shows 850 exactly

With a beam harbinger, T2 small drones are very good, as is a web and a tracking computer. Try to get a tech2 tank with specific hardeners.

Also, cap stability with an armor repper or shield booster is not necessary unless you want to afk mission. As long as you have a min or 2 cap with the repper going, you're more than good to go.

This is the fit I use on one of my characters, does 424dps(guns only) with her skills and Multifrequency (478 with all V). Optimal is between 26.9km (Multi) and 8.4km (Radio) with Optimal script. Might not be the most efficient L3 mission runner, but it works very well for me.

This fit "grew" with the skills, started out mostly with T1 (except for the tank) so it should downscale pretty well. At low skills tracking can be an issue so you will be relying on the drones for the frigs, right now I don't use the drones much for L3s as frigs melt before they get close and the rest the guns can track if I load a tracking script. Just make sure to keep your transversal to your target as low as possible, kite if you have to (or charge right at them and let them try to kite you if your tank can handle it) but whatever you do, don't sit still, this ain't a potato or a Myrmidon with an active repping bonus and pretty much infinite cap.

I don't really use Scorch often even though I do carry a set, I usually make do with Multifrequency M, Standard M and Radio M (frigs will fly right at you, so blap them early with long range crystals).

Critical skills imo are Sharpshooter (optimal!) and Motion Prediction (tracking!), those I got to 5 first, the other support skills are slowly following now (started with Controlled Bursts V) . And since you're flying lasers (omnomnomcap!) you want to get those cap skills up asap as well.

HTH

Radio has a longer range and is quite enough for my purposes. And it doesn't wear out = cheap. If cheap works, why pay?

There's a few missions with heavy incoming fire that I want to whittle down asap, then I use Scorch, those are few and far inbetween though.
