That's a good start to focus on what you want. I would get a visual Hypo to increase your chances of hitting the Mimosa. But try to avoid getting a multi gene Hypo as that will certainly muddy the water and make it tough to tell what all genes are in the offspring. Go on Morphmarket and look at all of the Champagne Hypo (Mimosa) combinations to help you better recognize the sometimes subtle differences that the other genes can throw in that combo.
