Thanks for the numerous varieties that have been posted!
Any ID at this point on the (very possibly folk-processed...) specific variety that I described?  (I'm pretty sure I'm describing it pretty exactly as danced at Flurry '17.)

(For your convenience ;-) here again is the description: )
Formation: square with a cpl in the middle (i.e. 5 cpls)
A:
Middle cpl 1/2 R&L with cpl #1, which becomes new middle cpl
That cpl uses momentum from courtesy turn to turn twd cpl #2, 1/2 R&L with
that cpl
Cpl #2 becomes middle, 1/2 R&L with cpl #3
Cpl #3 becomes middle, 1/2 R&L with cpl #4
Cpl #4 becomes middle [turns to face current #1, which is orig middle]
B:
Couples currently along up/dn axis (heads+middle) turn back on ptnr, now
all can form 2 rings of 5, circle L/R;
Ptnr swing (some ppl may have to spin around to find Ptnr)
