[Callers] Butterfly Whirl

Hi Everyone, I'd like your advice on the timing and teaching of "flutter wheel with a butterfly whirl." Lots of dances use the following in a 16 beat section: Gents Allemand Left 1 1/2, scoop up Partner star Promenade, Butterfly whirl or Ladies Allemand Right 1 1/2 scoop up Neighbor for star Promenade 1/2, Butterfly whirl In Butterflies by Cary Ravitz, A2 is A2 Men allemand left 1/2 . Men keep left hands, pick up your partner, star promenade across, and butterfly whirl 1/2 to put the ladies in the middle. Ladies allemand right 1/2 Ladies keep right hands, pick up your neighbor, star promenade across, and butterfly whirl 1/2 (men go forward, ladies go backward) to put the men in the middle so allemande left 1/2, star promenade, butterfly whirl is done in a 8 beat phrase. However in American Gothic by Nathaniel Jack which starts A1 (around Neighbor) Mad Robin Ladies Allemand Left 1 1/2 (Scoop up Partner) A2 Star Promenade 1/2 (Ladies in the center) w/ whirl Gents start 1/2 hey by Right Allemand Left 1 1/2 is done in a 8 beat phrase, and star promenade, butterfly whirl is done in a 8 beat phrase. I tried this dance earlier this year with experienced contra dancers and many were having trouble getting through A2 in time. A1 Circle Left 3/4, Partner Swing A2 Promenade across, Ladies Allemand Right 1/2, scoop up Neighbor for star promenade 1/2, butterfly whirl B1 Pass Thru across (right shoulder), Neighbor Swing (face down four in line) B2 down the hall four in line, Turn alone, come back four in line, 2's in the middle make an arch and pop the 1's Thru to the next couple. How do you help people with the timing? I've tried to suggest that those getting scooped up need to be ready. Thanks. Cheers, Bill PS - in MWSD, right hand dancer allemand right 1/2, pick up person across, star promenade back, is called Flutter Wheel and left hand dancer allemand left 1/2 , pick up person across, star promenade back is called Reverse Flutter Wheel. Both are meant to take 8 beats. I have square dancers in my regular contra group and need to get them used to contra dance timing.
