Also, isn't Grasiani's the first line of pastels so it might well be that most pastels are his line, if it did matter.

It will be interesting to see if lesser and butter lines can be kept apart. At least with the other white snake hets so far I think there is hope that with a little work and the differences to make it possible one could sort a high percentage of the different types out after a cross. But when someone starts breeding a lesser X butter leucistic to normals will they be able to pick out all the lessers from the butters?

How about all the cinnamons from the black pastels when that combined super is bred to normal?
