My point is they are different lines.
No one has a problem saying Graziani cinny or pastel. Or BHB cinny or nerd lemon pastel. It is understood they are different lines yet the same morph.
I think this is the same concept adding the fact that no one has yet to prove the Fires and Sulphurs are compatable. That is an assumption untill proven to be genetically true.
I understand where you are coming from but just because the supers are similar doesnt make them the same exact morph quite yet until proven and even then they would still be different lines.
Vin Russo's, mojaves, butters and lessers make BEL's but they arent the same morphs?
I have seen Amirs black eyed line hets (hypo glows) in person and they are visibly different than fires yet they produce similar supers.
It is important to distinguish lines so future breeders can have more knowledge of the genetic pool they are working with and make there choices accordingly.
