With my regular planets I have 1 Launchpad, 1 Storage and 6 or 7 BIFs, I route the extractor stuff to the storage, Storage to the BIFs, BIF’s to the Launchpad. I set for 3 day cycles but reset after 2, if the LP is getting full with end product I move it up to the POCO and collect once a week.
What is your set up, why do you have to route anything other than what you have going to the factories?
