And remember if you are running a fast transport ship with no intention of stopping to fight, than you can undersize things like shields and power. This saves weight for speed. An outsized or over engineered power plant just generates heat and weight you don't need. Not fighting, than you don't need to carry weapons. They would just add weight, slow you down, make you think too much and raise your rebuy unnecessarily. No shields, than you don't need those shield boosters either. If they can't catch you they can't hurt you. Thrusters. Focus on your thrusters. And bulkheads. Military or Reactive Surface Composite gets you enough protection to deal with hits and still get through things in a relaxed fashion.
