From a column in which every other dancer is facing as though he or she were in a regular column and the other four alternate dancers are either facing out or facing the center of the set. Each alternate pair is either in a phantom column or a phantom wave. From this formation, those in the phantom waves circulate in those waves and those in the phantom columns circulate in those columns. Finishes in T-Bone formation again.
