What you say about ranking missions is totally irrelevant. I am already King and Admiral, why would I still go there if it was just for rank up? It has RICH MISSIONS, period. Nothing to do with ranking. When I want to make Biotech conductors, MEF, EFCs, I toss a coin between Sneider Enterprise (TZ Arietis) and Galileo (the Moon, Sol), because I know I'll find a mission I WANT to do that rewards what I want. When I just want to do some federal dirty work I'll go see if the President needs any Independents killed.
Tiana Fortune cannot apply special effects to FSDs (avoiding a long trip to either Farseer or Martuuk, if you are in the core systems), nor engineer G5 FSD interdictors? You've confused me here, because even if she was superior, which she isn't, I've never visited her except to rank her up for completeness, and moreover, she's not in Sol...we're talking about useful stuff 'in Sol'.
Outfitting is irrelevant, the core Fed systems have the highest concentration of High Tech systems of any other area of the bubble to my knowledge, plus it's only 70ly to Shinny, something most ships can do without a scoop.
