I also have to agree with you, but I also throwing this out there aswell. I think all three(Mojave,Butter, Lesser) are all the same morph with various lines.
The range is huge in coloration and pattern between Mojave, Butter, Lesser complex, but this is widely accepted in the pastel morph with various lines that all look very different. I have seen some screaming pastels, with some that I can barely tell is a pastel.
Not to mention the fact very few people can identify a Mojave, butter, or lesser with 100% certainty and get it correct. Also I have never gotten an answer on the breeding of Mojave X Lesser producing BEL's. To me thats the nail in the coffin.
What I think would be good for the snake community would be to just make them under one name and just go by quality, but I think there are too many people who would cry about losing tons of money form their high priced butters/ and some lessers.
