So I've recently gotten max reputation with Omega Task Force and will be working on getting a ground set soon. Problem is I have no idea what set to get. I'm an engineer with a preference for the Fabrication Specialist Kits and my Romulan Flamethrower.
The MACO or Adapted MACO sets work well on an engineer. The MACO set is nice because the shield healing from the set scales on your Engineering Repairs skill point box. Adapted MACO is nice for the reasons outlined above by futurepastnow.
