[Captain Kwok]

An easy way to balance ship sizes in a mod is to keep the same engine:weapons:hull size ratio for all ships, i.e. QN propulsion while modifying mounts to provide the same damage/kT ratio at all sizes. Of course, the smaller ships will have their defense bonus due to size while the larger ships are more likely to provide that crippling blow. This works even better in a leaky armor/shield setup.
