I would grab the breeder sized females. The het pied girl to go with your pied male, and lesser female to go with your Mojo male, if possible. If not, then absolutely grab the yellowbelly girl, those are always fantastic to have.
You'll make than half your money back just from the het pied girl the next year.
It's a business, right? It may not be the most exciting choice, but it's probably the most solid.
