Functionally, PJ's inside ski becomes his new outside ski while it is on its LTE and finishing the old turn.Functionally, it becomes his new outside ski when he begins to transfer his weight to and move his body into the new turn.
This old/new outside/inside timing is one of those such issues. Starting the new turn early is a key issue in modern skiing - and one of the very different timing issues from the more classical turns. It is also what the men's USSA team is currently working on - or was as of a month or so ago. So, it's quite the up-to-date issue.
Getting this early weight transfer and movement into the turn, also depends on how you think about the turn - if you think the new turn starts at edge change, then you will have a hard time moving early enough. If you think of turns more of going from apex to apex, then it's easier to move earlier.
Hate to burst your bubble Cookie, but the concept of the turn going from apex to apex was discussed well over a year ago here on Epic, so it's hardly new to us. Maybe somebody here remembers where it was and can add a link. I've long since forgotten who said it.
I'm not buying the sentence above - if you think the new turn starts at edge change, then you will have a hard time moving early enough. All this means is that you were not accurate with your pressure management in the controlling and finishing phase of the turn. (and it's called the finishing phase......because ?)
Here is the best litmus test I know (brought to us by Jim Vagani who is an eastern DCL) We were discussing something along these lines about 4 years ago and this is the point he made;
"As far as the inside and outside ski goes just think about it this way. If one of your skis was to pre-release just think about which ski you would rather be skiing on, that would be your outside ski."
You also said ".......then you will have a hard time moving early enough." Early enough to do what? This is a matter of the skiers intent isn't it?
