How about a special Banana Black Head GHI Leopard Orange Dream lady? That would produce a huge spectrum of awesome snakes that are all desirable. The unfortunate part is that you don't take advantage of the 100% het Carmel in him, so you might not want to go with my opinion.
In all seriousness, we have no idea what you like, what your price range is, or how soon you'd like to breed your boy. Remember, she (and any potential offspring she produces that don't sell right away) will be in your possession. Choose a female that you both enjoy looking at every day and would be excited about every single possible baby. That's one of the best parts about this hobby!
