For the Maia trip you could just switch to a Hauler if you’re cash starved.
A Hauler with an A rated FSD and everything else D rated can jump around 30ly, usually makes it in 20ish jumps.
Was running a Chief recently but I was trying to do CZ in one, thought I had a nice set-up with my lasers and multi’s but it was taking forever for things to drop. Switched to all overcharged multicannons with auto loader/corrosive and the difference was amazing.
Seems any thermals on your ship just slow you down in CZ these days.
I’ve upgraded to a Krait2 with the same setup.
The Fed and Alliance ships are built to be hull tanks, you can however change them into nice shield tanks with guardian shield boosters, but that’s probably a discussion best had after you get through your initial engineering phase.
