Could the WC have been a granite also? Some of the cinny sibs look like they have some granite in them.
Granite type gene would be my first guess as well. As Neil said, super nice Supers.
The stripe should NOT be there!! Something is going on I would think. Will look forward to seeing them after a few sheds. Great project.
I would grow a super boy up and put him on a couple normals and a morph or 2 -- Y.B. and Pastel maybe -- in order to see what is happening genetically?

I'll take two! Those are some gorgeous snakes! I can't even imagine how stoked/stumped Tom must be, what an exciting project. Can't wait to see that lil super after its first shed.
