I would also vote for the cinny het gs, if you're set on one of those two. I am personally a big fan of variation. You have a lesser already (albeit a female one), and seeing as how you have no interest in a BEL not to mention the potential deformities, the cinny would be the way to go. Cinny lessers are pretty, pewters are cool, albino cinnamons have nice contrast. But I would personally work on getting more females at the moment, as males take less time to become breedable.
On a side note, already looking for new additions again? You little addict, you.. xD I'm totally jealous. :o
