I asked body python or fdl, answer:
well I went: cobra --> asp --> type 7 ---> python ----> type 9 ----> anaconda
then I bought fdl for piracy and warfare. Was picking between python and fdl, went with fdl and I'm not sorry.
it's really fast, shields are great, no one can run away since you have them mass locked, cabine is a bit fucked up, but it's also quite cheap to fit and insurance isn't expensive either.
but for credits you should really try to get type 9 and should go over python (it can be fitted nicely for trading 230-250t or so cargo). Don't remember what cargo type 7 has, if it's the same you can skip python, I just hated that craptype 7, it got the job done but [edited]kept overheating and was low quality
But type 9, if you're in chona, you should really get it. That thing is credits printing machine. with that thing in possesion or anaconda, you can buy anything anyway and it's just few more hours of trading to get it. I was getting 6 mil per hour in chona with type 9, so that's like 9-10 hours of trading and you got that python or fdl.
