Solo Nullsec Hunting / Probing / Cover Ops T3 Cruiser

Greetings,

I have flown lots of ships in Eve but not T3 Cruisers. I have the skills to fly any of the races T3 Cruisers.
I would like to build a Covert Ops, Combat probing cruiser for Null / Low Sec solo hunting. With the change to Local in Nullsec this seems more viable.

Any suggestions on best ship? I am thinking either Tengu or Loki? I need to fit expensive mods or can I just got with T2 garden variety? Need implants? I do not want to have to off line mods to scan probe.
I did find some fits but not that familiar with T3.

Thanks for any help.
