The way you build your collection is totally up to what your goals are. If you are shooting for pieds, Buy a bunch of 2010 100% Het girls and in 2 years buy a visual male.
I personally would go the co-dom/dom route. I would buy some 2010 pastel females, mojave females, spider females, then in 2 years get a hatchling combo male maybe a lesser/pastel or lesser/cinny? That would give you a bunch of different combos/morphs to hatch in about 3 years. I wish I did it that way...lol
