Lightning Pied?

[Badgemash]

Or to improve your odds breed the 100% double hets to a visual of either morph giving you (in theory, which I hear is a great place to live) 50% visual morphs. These would be a mix of either pied or axanthic(depending on which visual you bred the hets to) and lightning pieds. The single gene morphs would then also have a chance of being recessive for the other gene and the "normals" would be 100% het for the visual gene and 50% het for the other.

You still have to treat the critters well and, burn a ton of offerings on the altar of the odds gods. But, it should improve your chances.

I'm actually not going this route with mine specifically to avoid 50% hets, I feel like it just adds a third generation into the process of trying to hit the visual double. With DH x DH at least everything else is 66% het and you at least have a (small) chance of hitting the visual double.
