I prefer Pure + Pure Dark, because it means that the only egg I have to sell is the Pure. xD I'm farming Pure Darks. The Big Dark Habitat caps in less than an hour with 4 Pure Darks. xD

Incidentally, I'm not getting much benefit from the Dark Crystals. Its range is so short. =< Maybe it will work better on the Pure Habitats. After all, you can only fit two Pure Darks in a Pure Habitat.
