I think we are comparing two different things. Z plied thread will keep more of its twist while working than an S plied thread. Twist motion is z twist so z plied threads will not loosen while being made into lace. S plied threads will lose their ply twist ergo 'soften' while making lace. Sometimes though you want threads to soften. Early lace was made with less ply twist on purpose. So, in my opinion, if a tradition calls for a certain type of ply twist, it did so on purpose. Sue M
