IanG Line Black Pastels are like 300ish and produce the most stunning black supers and black combos. Get a female, breed it to a male Pastel, then take any male pewters you get and breed them to that female BAM silver bullets and super black pastels. Well if you're lucky ~_~

Mind that an IanG Black Pastel will be my next snake purchase, and I absolutely adore what they can do genetically (where as I think Cinnamons just fail to pull it off).
