Skiing is still a sport and to those of us (myself included) that were never top athletes in any other sport it is going to difficult to be an expert skier because natural athletic ability is required. So reading about Pinkie Leads the Way has not helped you? I would think all of the reading here should have given you a leg up on the movements to make you a better skier. My learning style tends to be Kinesthetic so I have to actually be on the slope and that tends to limit my learning time.
Don't sell yourself so short.
There is a ton of great knowledge being disseminated here. BUT, participants need to have a fundamental understanding of underlying forces that dictate the mechanics. It ain't all about youth and physical ability. At 68, I am skiing athletically worse but technically better than ever . And a lot of the credit goes to many who participate in these forums and produce videos on YouTube. But like many things, without a "workings" knowledge base, it's LET THE BUYER BEWARE!
Example:
While "Pinkie leads the way" might help some, it is no way a fundamental movement pattern. For a more advanced skier moving at speed, it may be a helpful tip but at the beginner level this is a major miscue IMO.
The reason is that skiing not only requires us to dynamically balance on a moving platform, it requires we dynamically balance against two competing forces, Gravity and Centripetal. The former is constant, ever present and the default, the latter is developed and rises and falls due a combination of skier actions and variables.
At the advanced level, Leading with the pinkie toe may help with timely participation of the inside. It helps the inside "clear the way" and better positions the skier to handle the soon to come centripetal force being rapidly generated by the primary outside ski.
Telling a skier at the beginner level (who is in a wedge configuration) to have their "pinkie lead the way" will move their mass to the inside because (at the time) they are relying on gravity for balance and there is little centripetal force in play. This flies in the face of PSIA fundamental #2 "Direct pressure towards the outside ski".
If we can agree that the real problem we are trying to solve is getting the inside to clear and participate in the turning process we need a solution (a movement pattern) that works with the beginner as well as the advanced skier.
Looking at it from that angle you might want to consider that the fundamental movement pattern is not so much leading with one's pinkie toe but a softening, then shortening of the inside leg.
For the beginner doing this under gravity, it starts the flattening process of the inside ski and automatically moves the COM towards the outside ski. For the Advanced skier, the shortening process helps keep the legs parallel (what leading the pinkie is trying to do) and in sync with one another other just like a bicycle and properly begins a movement pattern that becomes more active and important as the turn heads to the completion phase.
