My Zeena is white (as yours'), and is what would be called "smooth", but is very "fluffy". Paired with an unrelated gray smooth breasted gander, they've produced almost every color and feather type, from extremely curly to almost smooth, and every color variation imaginable! The smooth Sebs have their own standard in Europe, and are often paired with curly s' to keep genetic flaws from surfacing in the offspring. It's up to you if you want to let her breed, but if you do, I would match her to a gander who's not a sibling and has some curls-my opinion. Color is to your preference. For the Zeena and Zander pairing I have no clue to the color of their parents. All of the other geese I own now, I do.
