CAUTION: The A is not really do-able as it stands.  Needs more tweaking.

I could try a tweak with setting without turning single or turning single without setting to allow more time for the chase.


Bouncy jig
Silly dance, not regency:

Second corners set forward, turn single back,
 chasing out the gent's line (L1 in lead)
right around first gent to finish
in corner's place.

First corners set forward, turn single back, 
then gent in the lead, chase out the ladies line
left around second gent (in first corner palce), and finish in corner's place.


B:

Same four, starting partner, circular hey once round.

Same four, circle left once round, partner two hand turn 1.5 and face new neighbors.
