The newest addition to my fleet - a Vulture. Configured to do two things - tank, and run warfare link modules.
It does both superbly. the warfare links go a long way to mitigating Nation infection of local data networks and ship systems. Most of my work is filtering out the imperfections in the shielding systems of my comrades, but it makes an enormous difference to the ease with which we can excise the Sansha presence.
As for the tanking part... well, passive buffer tanking is one of my specialist fields. There's a reason I called this ship the "Unbreakable Vow".
May it live up to the name, and keep the skies of New Eden clear and safe.
