I realized a good while ago that I can't work with all the BP morphs. It is impossible for me!
So, I pick the ones I really want to work with.
Also some are very close. Such as mojaves, lesser platinums, and butters. There will be plenty folks on the forum to disagrre with me here, but of the 3 listed I chose to work with lesser platinums. There's plenty of times that I wish I had a mojave project going on ,but I know that I can't work with every thing available.
I got my first BP(female albino) in 2003 and you already have as many BP's as me. Hope this helps!
