I run slaves and imp slaves as trades. Illegal in almost all systems.
I sell them at black markets. I line up for the entrance, ask permission and fly in at full speed. Did this with the cobra, later the type 6 and now with the ASP.
1 out of 25 times I run in like this, I hear them scanning, but I'm in the dock by the time they finish, so no sweat.
No need for heat sinks, no need for silent running. In fact: Most of the time I throttle back to the blue (more maneuverable) just prior to entering the letter box.
