When you fly a pirate, 90% of the traders you'll encounter will at first try to escape silently.
When you fly a trader, 90% of the pirates you'll encounter will just go "2milordai".
Myself, when flying a Rogue, I often like to make use of the /dice or /coin, whether the trader have to pay and how much. However, most of them blow up because they don't roleplay since "time is money".
