That pushes 750 dps with drones that move 7400 m/s and track at 1.1.

I don't personally know how the EHP would hold up (meh resists, 60k ehp under links), but drone travel time would be almost negligable, and you'd probably speed things up quite a bit with your heavies instablapping frigs without issue - no webs required.

If you can bring skirmish links, your sig drops pretty low so you can start sig tanking. Additionally - Halos are very cheap for a pirate implant set, and would further reduce your sig letting you tank even better.

Alternatively, a proper Slave + Hardwirings set gives you 95k ehp, for a bit more buffer against high volley waves.

You lost the instant dps vs contests, but I can't imagine it being that horrible once you catch up, and your completion times might speed up with the frigate factor.
