Missions & Complexes

Sorting through the loot and selling it shouldn't take nearly as long as people are saying. There's very few mods that are really worth saving to sell in Jita (sell price > value of reprocessed minerals), and if you pay attention you can learn them all pretty quick. The vast majority can be reprocessed without thought. I'm assuming you have good reprocessing skills, which your noctis alt should have.

Going through mod by mod and comparing sell prices to reprocessing prices can improve your margins a little, and so can setting up (and babysitting) lots of sell orders. But neither of these things is worth the time for the marginal ISK increase. Just grab the big ticket items and move on.

Edit: Big ticket meaning items who's sell value >> reprocessing value. Not necessarily items with a big sell price. Almost all of the big guns sell for a lot but the minerals are worth just as much.

Some of the LP ratio's in this thread are way too high.

Looting/salvaging the missions will make you a little more with a max noctis.

The best way is find a newer player to clean up behind you and split the loot/salvage.
Both of you will make more isk.
