I think you need to go do a little bit more research on your history. Do you realize that Graziani and McCurly produced the first Pastels the same year. Then they both sold animals before they were proven to have a Super, or that they were proven to be compatible. Yet 10 years later, we still have NERD Lemons and Graziani Pastels. I also would like to know what you mean by Sulfurs being unproven? Are you talking about wether or not they are proven compatible? As far as that goes, NERD has a line of Axanthics, but has yet to test compatibility with other established lines. What do we call those Axanthics?
