Yeah but a Lesser Mojave is not the same as a Lesser Butter, you can distinguish a Mojave from a Lesser, but that task is not that easy (some say impossible) with a Butter and a Lesser so if i want to work with a Butter project, my choice is not go to a breeder who has those lines mixed because at the end the breeder could be selling you a Lesser saying it's a Butter because at the end, both morphs are in most case undistinguished. The same happens with the Cinnamon and Black Pastel etc etc etc.
I understand someone who says that they don't have any problem with those lines been mixed, but no one can tell me that there is no problem with that issue and for example you can work in a Black Pastel project using and 8ball for example.
