I thought I'd saved a fairly recent discussion on 'transgressive contras'...there was one posting that had a link to a video of 2 contra lines where the 1's bounced back and forth from line to line in subsequent verses. Could some kind soul who did save that please email me the link and any relevant discussion they saved at
catherineaura@yahoo.com. Sadly I do not know how to access any archives...tried googling 'transgressive contra shared weight' and just brought up a long discussion from 2006
