It is a complcated decision given the problems with super black pastels.

In terms of slow but consistent returns I'd think of looking for lavender albino pieds ( dreamsicles) or if you are set on pandas I'd think of at least trying black pastel/ cinnamon combos they try and mitigate the problem. Or somethng else in the same complex - i seem to remember mahogany being on the same locus?

I might be wrong however so wait for confirmation.
