The Hauler!
When you have lakon 6 or above the recent haul missions will become pointless since you can earn 100k+ credit trading goods from station to station meanwhile the mission only gives maybe "9k" reward.
This is true to an extent, its all about the profit per ton. Even while I'm running gold or palladium making 155k+ I'll still check the bulletin board. But the mission must meet the requirements of: A) being delivered to the same destination as I am already headed to (or to a scheduled fuel stop) and B) have a greater profit per ton. Only then will I spare the room in my cargo hold.
You might be getting "9k" for a single ton of cargo. So far the best profit per ton I have seen through regular commodities trading is roughly 1.5k.
