I really like 2 DHC, 1 DBB, and 1 Torp up front with a Torp and 2 Turrets in the back. If you can keep energy levels up, using the full DHC/Turret build is nice but it feels like you lose out on burst damage (even those that's some nasty damage over time). I like the Torpedoes for energy free burst and some really incredible crits against naked hull. The DBB is for Beam Overload which can actually gimp your DPS for a bit once you've fired (and if it misses you can be a bit vulnerable until it recharges) but that's what Weapon batteries are for. The turrets in the back, as opposed to single beam arrays, have a 360 degree firing arc so with proper power level management you can add to your forward damage.
