out of curiosity, what are you considering cherrypicking, searching a minefield for just one ore and mining just that ore, or are you including searching a minefield for one ore and emptying whatever roids you find with that ore in them? I admit to being guilty of the second example lately while looking for Osirium for (what appears to be) a bugged mission. BTW I should mention that if you stick with fields that contain only one type of resource (rocks, glowing rocks, crystals, or clouds) JEs and possibly PSs shouldn't run out of cargo space, it's the mixed fields I have trouble with on my JE.
