US: cluster redesign

It is my hope that the issue of balancing 'toll' and 'untenable costs' is one that results in a choice for players to play with, and not a forced choice. In other words, a player should be able to choose to play the legit and standard routes, pay the customs duties and tolls they have to and still succeed at the game. A player that chooses to try to avoid paying these fees in order to accelerate their financial growth could choose to risk taking the unstable routes, but the hidden costs of damage and pirates may make this almost as costly (maybe more exciting, but...). This way, it becomes a play-style driven choice (high risk vs low risk), and not one that is so tough one way and so much more relatively manageable the other that it ends up not being a real choice at all.
