Maybe the strategy advice could look more like this:
1. Draft him when there is
a shortage of resources on the cities. no completely obvious other pick.
2. Focus on
Contracts. nothing particular, Mercator is pretty flexible.
3. Travel to resources
but dont bother too much about travel missions. and usually aim to fulfill your travel missions unless they are completely crappy (which shouldn't really happen as long as you play with 'pick 2 from 4' expert mode.)
