You might look to nearby _systems_ for sourcing superconductors.
The reason is that its much faster to jump between systems and SuperCruise to target station than it is to SC from one station to another within same system…
…time taken to get up to 87MPH and 1.21 “jigga”watts and jump systems is shorter than reaching escape velocity of local body during in-system SC – by a fair margin
Oi! That's Baron von Schnellenstein to you, mate. No, it doesn't matter that I'm an Imperial Prince!
