first, that Butter Mojo (poss Pastel Leopard Blackhead poss het Pied) u linked and was interested in has a buggy left eye. alotta peeps try not to breed "defective" animals. (it sold already anyway.)
second, are u interested in breeding to make something colorful or to get some cool patterns? maybe both?
i think something like a girl Leopard Mojave or Leopard Lesser/Butter would go well w/ both your Pastel Enchi and Banana. u will get a nice variety w/ your Pastel Enchi and both nice colors and patterns w/ your Banana.
actually now that i think of it, your Cinnamon would go nicely w/ your 2 boys. if u want something else and different, IMO Champagne goes nicely w/ Cinnamon.
LOL!
