I'm currently in the process of picking up the first of the three additional females. Found a very nice pastel YB female and working at getting her bought.

Pastel and YB don't do much for me singly, but together they are great. Both good mixers with most other stuff. I'll be using this new female to not only get het pieds with but also eventually for mixing with non-pied males. She will give me a good range of breeding possibilities.
