Ping Pong Circulate
 

From a 1/4 Tag position (An ocean wave between two in facing couples):

* The outside couples move forward to replace the dancers in the wave

* The end dancers from the wave move to the outside couple position,
trading so to face back in as to always remain outside of the center
dancer from the wave (Stay on the outside track!)

* The center dancers from the wave move to the outside couple
position, trading to face back in so as to always remain inside
of the dancer from the end of the wave (Stay on the inside track!)

The wave in the middle will remain right or left
handed as it was at the start.

The inside and outside paths are independent of
each other; either or both may move
