Doing some rough numbers leaves it with a strong tank (well over 13k ehp), a rack of 7 small rails, a micro warpdrive, along with a spare mid slot and high slot. I don't have access to a fitting tool with the updated stats yet, but I feel the following will be the cookie cutter Eris fit for small gun orbitals.
7x 75mm Gatling Rail II
1x Limited 1MN Microwarpdrive
1x Damage Contol II
2x Energized Adaptive Nano Membrane II
1x 400mm Reinforced Steel Plates II
1x Small Anti-Explosive Pump II
1x Small Trimark Armor Pump I
Sadly I remapped away from ship skill attributes today before these changes came out and have no skills in interdictors. I will be sure to have my friends who can fly them try this fit when the new faction warfare changes come in though.
