As someone who favors small, frigate only strike groups the Silverfish series has become an instant favorite for me.
They can carry more cargo and fuel than a Cerberus, run just as fast, put up a fight (the B variant can spank just as well as a Lasher), and above all they have a shield! And all that for some armor reduction.
With the right configuration the B variants can even replace combat frigs. So nasty.
But why did you choose to jam a weapon in the 00 Series large slot instead of leaving it open for customization?
