Really interesting!! I've been having thoughts about this myself. Watching videos of elite swimmers and the power they get from their legs I was struk by this scissor movement where one leg is recovering (rising) as the other is kicking (descending). But is that possible with a 2bk? Seems to me a great way to tame the splayed legs but via a 6bk?
