I really like the "extra-dirty" super mojaves that have visible pattern on their sides. There's a market for those, just like there's a market for "extra-dirty" ivories... and my husband seems to think the pure white snakes are "creepier" than the white snakes with patterned heads.
But pure white snakes certainly sell well, and people are currently asking slightly more for lesser-mojaves and super lessers than they generally are for super mojaves.
Anyway. I think I'd start by breeding whichever snakes are ready to go first.
