You can either run with the cookie cutter build (featuring cutbacks to everything in the name of a couple of LY extra jump) or do it to your preference.
Cookie cutter builds can be found everywhere on this forum. For exploration they are pretty much one and the same thing for all ships, adjusted slightly to fit into or take advantage of differing internal space levels.
But as for any kind of personal build, only you can decide what you want. My only real advice: take a damn fighter. They are much better for buzzing around an asteroid field in than the 'conda itself, and there's no real penalty for smashing the fighter into a floating rock.
Seconded. I missed not having one on my trip to Beagle and have now added a fighter hangar at Colonia.
Fighter hanger - is this of any practical use or just simply to alleviate the boredom on a long trip?
@ StiTch: I wasn't sure I understood how it could help in asteroid field as it can't assist in mining for mats in any way; can it???
