I happen to know a bit about the rattle used in that pvp video. Below is a sample:

I assumed that video was before new drone dmg mods etc were released thus didn't use them. Above fit is gimped a little (lol)by sticking to purely T2. 2 of these feeding each other its cap stable, local shield recovery of 700/s each snake. With a few tackle and support help the duo is quiet fun. resist 61-69-76-86

If you are willing to throw down the money, the numbers get exponentially fun. Below is a ridiculous fit (well, to some. Some of us consider 7-8b pocket change )

this one mainly aimed for tank and still rely on tackles. resists80-81-86-88. duo feeding off each other its cap stable and.. local shield regen of 1500+ hp/s. in order to break this tank you need about 7500dps minimum. It can also handle a neuter or two as itself also neuts and can free up quiet a bit of cap regen by turning off neut/1 energy transfer on the ship being targeted.

there's also a nano tackle fit which is hella fun when you use it to duo or small gang roam. but...I'll keep that off of table for now .:p
