The super fire also produces patches in the yellow sections. Fire mojaves and yellowbelly's have also been produced and look the same. I personally do not know the difference in price between the two. As far as different lines the animal should still be the same mutation for namesake. Cinnamons and Black Pastels are vastly different in appearance and the combo morphs as well as super forms are different looking snakes. Much more so than the Fire/Sulfur. This is not only about the fire/sulfur as well Tim. I would like breeders to be more honest to people who may not know the difference between the animals. I guess my point is why keep making the mutations more confusing with Sulfurs, Goblins, Flame Hypo's and whatever special "Lines" may exist? If you line has to be special throw your name on it for easier identification Ie: Envy's Line Fire. And let's say my line fire does prove unique in the long run I can then appropriate name it as a new mutation and anyone who purchased a Envy line fire knows they have this new mutation.
