I'm trying to maximize the DPS on my advanced escort (for PVE and PVP). I'm not the greatest pilot in the quadrant, so I find myself at more than a 45 degree angle from my target a lot. I've tried using regular (not double/quad) cannons on my escort, on the grounds that more time actually hitting is better than more damage when I hit. Is this nuts? How can I improve my build? Here's the build. I'm not looking for burst damage, but DPS over time/average DPS.

All of my equipment is level XI except my level X engines.

Fore weapons: Polarized tetryon beam array, photon torpedo (dmg), tetryon cannon (crtH*2,dmg), tetryon cannon (acc*2, crtH)
Deflector: Jem'Hadar
Engine: Hyper Combat
Shields: Jem'Hadar (I also have Paratrinic and Reman, but I'm not sure which is best)
Aft weapons: Tetryon beam array (dmg), photon torpedo (crtH), tetryon turret (crtD, dmg)
Devices: Subspace field modulator
Engineering Consoles: Green neutronium, green RCS
Science Consoles: Blue biofunction, blue shield emitter amplifier, purple sensor probes
Tatical: 3*green tetryon pulse generators, blue photon detonation assembly

I have attack pattern alpha, attack pattern omega 3, cannon scatter volley 2, beam fire at will 1, torpedo high yield 3, tactical team 2, target weapons subsystems 1, science team 2, engineering teams 1 and 2 (I know I need to do something about that), hazard emitters 1, and transfer shield strength 1. Getting cannon rapid volley is on my to-do list.

I own the full Breen set and a bit of EC, and I'm fine with replaying missions for better gear, though I'd also like to have a better idea about what my long-term grinding goals will be.
