Still best for surviving ganks or going AFK without caring, but this time with more drones and speed and even less yield than before.
Max yield drops from 16.4 to 15.2 but is 15% tougher. Ore hold fills in 13.2 minutes.
Procurer fit for yield is still tough as a brick, but still 18 cubic metres yield, down from 19.2, but still tougher than in Odyssey even when fitting a survey scanner. Ore hold fills in 11.1 minutes.
For ice harvesting, the max tank Procurer is still stupidly tough, but IMO it’s definitely worth using the ice harvesting rig because you do have EHP to spare. (fills in 13.5 minutes)
The Procurer can easily sacrifice the suitcase and a rig slot for max yield, yet still be quite difficult to gank. (fills in 9.8 minutes)
The Retriever was too popular, so its yield has been nerfed to counteract its effortless AFK isk.
Retriever fit for max tank is the same yield as a Procurer. At least the transverse bulkheads are a massive improvement. 19k EHP is pretty decent against a solo ganker. Ore hold fills in 30.1 minutes.
The Retriever yield has had a haircut so it makes sense to tank it up a bit since you’re obviously not in it for the yield so much as the AFKness. Fills in 25.4 minutes.
The max tank Retriever aims to maximise survival against a single ganker while getting some sort of ice while AFK. Fills 26 blocks in 25.7 minutes.
The ice yield Retriever aims to not be uber-tanked, but just less desirable than the Retriever next to it. Fills 26 blocks in 21.2 minutes. (Feel free to swap the survey scanner with a small shield extender II or meta thermic shield resistance amplifier)
Now boosted for even more yield at the expense of everything else.
Covetor yield is now 22.35 even with a damage control (this is for solo usage). In a mining fleet situation, you won’t need the scanner, and you’re probably better off with shield rigs because you’re likely to be receiving shield gang link support. Ore hold fills in 5.2 minutes.
Max yield Coveter is 4 or 5% better than in Odyssey and hasn’t changed much. Note the shield fit, to take advantage of fleet bonuses. Ore hold fills in 4.8 minutes.
A minimally-tanked Covetor is still squishy. I don’t like it. Six blocks takes four minutes.
The max ice Covetor is short on CPU so a processor over-clocking rig may be needed. Six blocks takes 3.64 minutes.
So, there you have it. The transverse bulkheads are great for solo use, especially on the Retriever and Covetor,
but aren’t as good as shield rigs if you have fleet boosts. The Procurer is a lot tankier and useful in High sec,
the Retriever is slightly nerfed but still the king of afk for 30 minutes play, and the Covetor gets a slight yield buff
to make it even more attractive for alert miners who are after maximum yield.
