Balancing Economy around such a route is horrible.
I have finished my work on the package that I was working on. Since this included pretty much the last changes that were necessary for the update to deploy, the only things that are required to be done are the economy changes and infocards, as well as bugtesting. Aside from that, I'll be taking a week-long break from Discovery, so any questions that you want answered would have to come tonight.
EDIT:
I will include a full changelog of the (system)update once it will deploym, or, if it happens before my break ends, after returning.
