Well didnt had a realy good planat in 9.5 yet but a realy nice star-system (with every Planet you want to have in one place). And since there a new items (and the way the market-shares/profit works) you want some dedicated Planet-Roles. Or in other words: one gas-gigant, one Farmplanet(without trans ore/vol), one barren Planet(aka vacuum) and/or one unhibated ore Planet).
With all of them in once place you get enough patrols to never worry about any expedition and still make more than enough money.
