Have you all encountered or written dances for a "reverse R/L through"? To my mind, this move might be any of the following:
a. cross the set with the lady on the left and gent on the right, lady courtesy turns gent (with the traditional CCW courtesy turn
b. cross the set with the lady on the right and gent on the left (as usual), lady courtesy turns gent (with a REVERSE courtesy turn, ie CW, as would happen on a gent's chain)
c. ??!?!?

Cheers,
Maia
