MAIN - Bretonia - New London - Waterloo Station - $8337
ALT - Gallia - Lyonnais - Roanne Production Facility - $13132
Main route is only 4 systems? how come? maybe you should change this to Liberty or Kusari.
Short ore routes are a general issue because they make cooperative flying unattractive and it benefits those most that just quickly want to get the fill, run there, get back fast in a credits / second race. In contrast, long ore routes are a lot more dangerous and they therefore make running together (and wasting some time in the progress) a lot more feasible. They enable players to engage in dialogues on the way and are better for gameplay in pretty much all aspects.
Therefore I am very much in favour of lengthening the really short ore routes.
Beryllium/Niobium from Tau 23 to New Paris is another one that could be +1 or even +2 system longer to make it more fun and in general more attractive (+ it would lengthen flying time in Gallia, which is also a good aspect).
