Here is my .02UEC....
Our home needs to be accessible to everyone in the Org., wether they want to put a hangar there or not. So, the low risk systems are out, due to high police/UEN presence, our pirate type members won't be able to make it without drawing an entire systems law enforcement down on our heads. And the high risk systems are out, lightly armed traders, new pilots, recently resurrected pilots in base ships will have a very hard time getting in without being shot to pieces. We need to find a system with at least 2 Jump Points, mid range security levels, and close to some major trading routes.
It will take some work, and a LOT of speculation, but I think we can do it.
