So getting back to the LF's original post. I feel like we have identified a number of skills or components of turn inits with a variety of approaches listed off by everyone. I'm not sure that really qualifies as one all-purpose init as asked. There have been many discussions in the past about OLR vs ILE, for example, two variations for turn inits. We have touched on pivot entries vs non pivot entries, another two variations. And I'm sure those are not the only variations, for example inside vs outside ski biases, etc. And many of these variations have a spectrum of blending possibilities in between.
Here are some of the component goals for turn inits I feel like we have identified thus far in no particular order and not necessarily consensus:
- releasing downhill ski
- tipping both skis
- moving CoM across
- establishing steering angle with pressure on new edges
- pivot entries if desired
- establish states of balance and movement such that balance will be maintained in the future through the turn
- establish states of posture such that centripetal pressures can be created or maintained presently and in the future through the turn
- establish steering angles and edge angles such that steering/shaping can be done post init if desired
If anyone can contribute to that list, please do.
The reality is that there is more than one way to accomplish these things. For example, some cautions have been made about not pushing out to bend the ski, about not thrusting the CoM across to the new inside and other suggestions. I think basically the above goals can be met a number of different ways, however some movements that I might consider ineffective might detract. For example, if someone pushes their CoM across, they may lose pressure on their inside edges, so doesn't meet the goals listed.
I think there are some systems out there that do narrow down the possibilities in order to keep things focused. Having focus on a narrow system can be very good for mastery, but not so good for adaptability. Nonetheless, there are numerous ways to approach things, and I think as long as the above goals are being met effectively, then its a good turn init method for the situation at hand.
Things can get more specific when your intent is more specific, for example if your intent is arc-to-arc, then maybe pivot entry is not allowed. Or skiing bumps might prefer retraction style releases and transition, etc. There are also differences of opinion and/or style on certain things.... For example, I intentionally left off the list outside ski bias, even though I'm a huge believer in outside ski bias generally speaking. My list of components for myself above would probably include more direct and specific language that includes establishment of pressure on the outside ski inside edge. I tend to favor a retraction style release and transition, so my personal l list would probably be a bit more specific then the above. My personal list definitely includes high-C turn shaping also, which basically allows only a tiny amount of pivot entry, if any, unless I'm going to skip high-C shaping out of necessity of some kind.
But nonetheless, there are numerous ways to approach it and I think if the above components are satisfied, then you can have an effective turn.
