Surprising you wouldn't be running a borg/aegis engine for a set piece bonus.
Meh.. With the Borg set, you can skip a part and only lose the tractor.. Borg Deflector/Engine/Console with a Capx3 or Aegis seems popular. (For obvious reasons, you get the hull/shield HoT, and only lose a stupid tractor)
I use Engine/shield/console on my Tactical Intrepid, along with a rare MK XII Graviton Deflector sporting [EM] and [TB] (Nice boost for my Repulsors, anyone have a better deflector?)
I use Aegis Shield/Deflector + Rare MK X Hyperimpulse [Spd] x2 (Which can outrun 99% of all other ships flying in PvP atm - And still have the insane defense bonus)
Ive even used Aegis Shield+Engine with Borg Console+Deflector on my DPS cruiser (which is low on hullheals, thus going for the hull HoT - Defense + Hullheals for a ship that has adequate shieldhealing).
