From waves or 2-faced lines (usually): 1/2 Circulate. There should
then be a center line and outer pairs perpendicular to that line.
The very centers cast 3/4 and Spread (outward) past one person. The outer
pairs Trade, and the inner one of them Spreads inward, past the people in
the previous sentence, to become very centers. The remaining person
Counter Rotates to become the very end. The result should be some kind of
tidal line.

This call can be started in any setup from which a 1/2 Circulate leads to the
required intermediate setup.
The initial 1/2 Circulate is a recognizeable first part, and hence it is
possible to do a Finish Cast a Net, which can lead to things like:
