I set 06 as main but unsure if it's the best one, might not have enough resemblance for some, but the 08 and 10 seemed to have small issues - grids available on the 04 version page.

The "Saki_new" versions were a bit more consistent with a "leg up" prompt during a short test, so if you have trouble with fucked up bodies or something of that sort, try switching to them - I think they're a bit worse with outfits, but shouldn't be any big issues and it's possible they're better overall.

Hair color, style etc should be changeable similar to other models, just weigh the prompt higher.
