Ok, Ill post my current weapons, consoles take to much time to post

Front:
DHC Aux x3

Aft:
Phaser Turret Mk XII [Dmg] x2, Tricobalt Torpedo Mk XI (Soon to be the KCB)

Power:
Weapons: 25%
Shields 40%
Engines 25%
Aux: 110%

I like this set up, I can make a pass on 25% speed and ruin their sheilds, then subspace jump and take 'em out with the quantum focus phaser.

Should work, yes.

Just not sure if the two turrets you use are actually worth keeping. See yourself if they do any damage at all. Getting some projectile weapons and possibly a beam array to use for subsystem attacks when strafing the enemy should work better.

Ok, I will try that

Assuming one has high Auxiliary and some good particle generators how much damage does the Quantum Field Focus Controller really do?

I have a friend who tells me he was a guinea pig for his friend who used one and said it wasn't doing a whole lot of damage, said was running high aux and particles.

I'm pretty happy with this, even though maybe you want to go cannons if you want more damage. I'm more a fan broadsides.

Commander Sci: Science Team I, Transfer Shield Strenght II, Hazard Emitters III, Feedback Pulse III;
Lieutenant-Commander Tac: Torpedo Spread I, Fire at Will II, Torpedo High Yield III;
Lieutenant Tac: Tactical Team I, Beam Overload II;

Equipment: Currently 2 Polarized Disruptor Arrays and one quantum torpedo fore and aft, full MACO, two RCS Accelerators, the Borg and Romulan set consoles, Shield Emitter Amplifier and Field Generator, 3x Disruptor induction coil Zero Point Quantum chamber and Advanced Danube runabouts (there might be pets that do more damage, but they have tractor beams and chroniton torpedoes which both inhibit the turning ability of your enemies, so turning away from your quantum wrath.)

I have a buld I got a friend to test (As I don't have a Vesta yet), he plays a tac and apparently it's power scared him.

This has been tried and tested and works a treat in STFs and matches a fleet Excelsior in pvp

You can use Single Cannons like the Excelsior... I ran Anti Proton versions on my Excelsior and my Vesta.

With this ship though, don't try to DPS like an escort... you cant. I focus on DPS crowd control where I use Gravity Well, Danube Runabouts, the 3 piece Temporal set to hold and destroy. Works nicely on STFs.

124 Aux, 7 points in Particle Generators, and 4x Mk XI Blue Phaser consoles, I get a little over 3.6K DPS listed after the changes to it a few patches ago.

Yup, that's pretty much it, for the 12s it's active, you get about 40k damage if you have at least 80 points in Particle gens and phaser tac consoles. That is, if you keep your target in the 45 degree arc.

In a science ship, you'll want high particle gens anyway. And you might want to use the (phaser) Aux cannons. Then the cost of running the Quantum focused phaser is just one console slot. Your choice whether to use it or not.

I beg to differ. Its about the only science ship thats of any worth in STF because you can run DHC. Single cannons are for ships like the whale/galaxy class. Use it to its strength, or else you are doing it wrong and wasted zen when you could have done the same thing on a regular science ship.

3 Aux cannons + 2 trico mines + Beam array is standard.
