Also would be a plus to reinforce the high tech blueprint. I don't mind it much personally but if each tech level is supposed to be the same and equal then why the hell is almost every high tech ship some sort of rare find.
I eventually raid Culann (almost) to the ground because Tri-Tachyon has too many exclusive ship blueprints and weapons. Few are shared by Diktat which is an even harder nut to crack and raid, and I do not raid Sindria for blueprints. I probably raid Culann more than any other industry world except maybe New Maxios, and I save Culann for last.
Raid order: New Maxios (easiest), Asher (Legion), Kapteyn Starworks (big pirate ships), Raesvelg (weapons and XIV ships), Culann (rare high-tech everything), Kazeron (Champion).
