Am guessing all your weapons are gimballed?
I've been using a combination of:
Slopey's BCP and
EliteOCR for finding/updating trade routes.
I've found that if I'm industrious with the taking and completing of missions from the bulletin board, sometimes 4-5 at a time, I can increase my credit balance quite nicely if I use Slopey's BCP to figure out what the best possible trade would be between systems I'm travelling too.
So at the moment, I have my configurationn
I've found a good hi-tech system in GD 219, so I at least know where to go to get some good stuff when I need to.
Once I can upgrade my weapons and then my drive so I have better distance capabilities, I may go for a wonder to another part of the galaxy!
