Byakuya's Ban-kai

So i'm sure that everyone knows that i'm a huge Bleach fan and i'm one of the only ones at my school that know a lot about the show. My firend wolfgamer was trying to prove me wrong and say that Byakuya had three ban-kai forms. Then i proved him wrong. Then at lunch my other friend Cameron was trying to tell my that Byakuya has two forms of ban-kai, and i think that he's just like everyone else with one form of Shi-kai and one form for Ban-kai. Who do you think is right me or cameron.
