Andrea kindly pointed out that half hey where you're about to pass by the left into a swing isn't the smoothest transition (without a balance); something I missed.
I see a couple ways of shifting that, like replacing the chain with a women allemande left 1.5; which is unfortunately their "non-standard" hand for that. Another way to avoid a left shoulder to swing would be ditch the lines of four and go straight into chain to facing neighbor then half hey, with a balance and swing neighbor in A2.
My sense is that accessible 4x4s really benefit from the lines of 4 to establish the set every time. Do folks have 4x4s that succeed smoothly without that?
Thank you all for sharing thoughts and dances.

A1 -----------

B1 -----------

(8) 1/2 Hey across, women passing right shoulders
