What gene's does your Lucy have? Mojave Lesser? I think that putting a clown in the mix would be great, the only downside is having to wait longer to get results because the clown gene is recessive, Albino might also be a good one, but thats because I am a big fan of Albinos. Hypo could be a good one, another recessive. I think a Champagne, if you can afford it, would be best, I believe they are around the same price as a Clown but they are not recessive.
