Ok, so I'm going to show my entire NON-nerdness and say that I really have no idea how I got this thing, I just flew by the seat of my pants. I was going through ships to pick for my advancement to admiral (what everone that is), and I looked at the deep space science vessal. Since it was the least flown ship, I picked it. I set it up with damage dealing tac abs, healing eng abs, and lastly, mostly damage and slowing sci abs. I called it the dawn treader (look for it in sector space, the ship is beautiful, 'specially with the paint job).
This may seem like a boring build...but...(well, the beam overload on the tetryon duel beam array looks like the photonic cannon from voyager)
It is a really fun ship to fly. Why? Because most of my abilities involve slowing or disabling my opponent and then deal damage to him in creative ways. I almost feel sorry for the jemmies when i tracker, matrix, grav well, and mine them to deal.
I don't use it so much for its damage as the ability to ensnare the ships. I have often use it for that purpose of my build is (sorry) traps. It's all designed to get opponents at a weakend state so that they can be easily finished off. It's worked with most of the ships I have come across, from cubes to klingons (although everything is effective against klingons).
