I thought it would be fun if we all voted on our favourite branch of the Sioux tribe. We've got the Unkpapa, the Sans Arc, the Minniconjou, the Oglala, the Brule, the Assiniboin, the Two-Kettle (don't let this influence you!), the Blackfeet, the Hidatsa, the Mandan, the Osage, the Quapaw and the Ponca.
I'm going Oglala.
