@Mike King, do you know why trainers promote "early pressure on the new outside ski" instead of "early weight transfer" to that ski? Or late weight transfer? This is a semantic question but it carries movement pattern content.
When people say "early weight transfer," that can happen as a result of several movements. One can remove weight from the new inside ski by lifting it or lightening it, both of which transfer "weight" to the new outside ski by default.
When people say "early pressure," it sounds like they mean something beyond "weight," something resulting from some kind of pressing... thus "early pressure" seems to mean extending off that new outside leg while it's still on its LTE, to "press" downward and put "weight" onto that ski.
"Early pressure" implies an extension to initiate a turn. "Weight transfer" allows for flexing to initiate the turn. And Delayed weight transfer implies yet another way of initiating. I'm wondering why the exclusive love for early pressure.
Your post above sounds like PSIA and/or your mountain trainers are exclusively promoting an extension move to start new turns. Is that the case? How come such an exclusive approach to turn initiation? You're not talking about bump turns only, are you?
