You demonstrated lead/follow switching in the “Trends For WCS in 2024” video.   I haven’t seen more videos on role switching here, so I hope this is okay to post, since it is complementary and not competitive with your site, but:

On his YouTube channel, Doug Silton recently posted 33 free instructional videos on WCS switches (within the same dance) and steals (“stealing in,” for three-for-all dances, birthday dances, etc.).  These videos were from several years ago, and were previously available for a charge (still are).
