I'm currently in the process of working that out. Right now I'm looking for ball pythons to get to breed with my recent hatchlings, and if one of my lesser pastels is a girl and one is a boy I'll be breeding them and trying to propogate my super spinal pattern (straight line connected to the eyebrows and jaw like my one lesser pastel). Mostly after breeding and seeing this line appear in one, almost 2, snakes, I want to start crossing that with other morphs. At the moment I'm really thinking a black pastel pastel with something else needs to come in to get bred with this line.
There are some genes I don't want to work with, but others I'm really excited to
