Firstly, congrats on the new 'Vette o7 I hope it serves you well.
Secondly, regarding credit making, unless I'm mistaken the best way to make space cheddar is still mining - Painite is the latest trend, or so I've heard. I was lucky enough to cash in on some LTD mining just before that was nerfed so I shouldn't need to top up the bank balance in a while (also, no fleet carrier lol). There's a great companion app that tells you where to find the best hotspot overlaps - http://edtools.ddns.net/miner
- if you're interested in that route. Also, I found my Python to be the best choice for mining due to it's large cargo hold.
