or anything that requires anticipatory balancing movements, a few c-forces and some uneven or pitched terrain.....
sure makes those first runs more enjoyable.

Numbers mine.This year’s breakthrough was (1) the realization that my COM wasn’t crossing over along with transitioning to the new edge leaving me perpetually in the back seat as the terrain got steeper and faster. In the past I’ve worked to improve my transition to the new edge always concentrating on (2) “skiing from the feet up” which I found an appealing touchstone, but seemingly (3) did little to get me out of the backseat. So, here’s my question, (4) why not initiate the new turn by moving my COM (top of hip bones) down fall line instead of my feet, or boots or knees or whatever is lower on the kinetic chain?
Pulling the feet back is a function of trying to get the body over the feet because we allowed it to lag behind. Or the feet to get too far ahead. As a corrective adjustment it makes sense but as a habitual strategic move it demonstrates a lack of skill coordinating simultaneous upper and lower body actions. Usually something corrected around U12-16. Watch World Cuppers and you will see a variety of transition where the feet and body play leap frog down the hill.
... depends on which way the wind blows... Could be reaching as well.
Making the claim that the body only "amplifies" what the feet do completely false.

Wrong!Focus on your feet, or focus on you COM; it is exactly the same thing. It is as with any form of instruction: good trainers look for the pointers that help their students to make the click. When I do Pilates my trainer gives me all kind of 'formal' instruction like 'use your powerhouse' (= abdominal muscles), but if that does not help me to do the routine the way it should be done, she says thinks like 'nose first'. That often helps me more. Apparently, the feet thing did not work for you. But things like 'pulling your feet back' (which seems to me the new mantra) is exactly the same as 'bring you center of mass forward' (old school). Same muscles, same result. And only the results count.
Apparently some folk do use hamstrings to move their CoM forward (e.g. dj61), but many don't. Hence the need for a GOOD instructor who can see what their student is doing in response to their instruction and adjust accordingly.Wrong!
Not the same muscles at all.
Feet back- hamstrings.
Center of mass forward- other muscles.
Can't see how you could use the hamstrings to move the com forward.Apparently some folk do use hamstrings to move their CoM forward (e.g. dj61), but many don't. Hence the need for a GOOD instructor who can see what their student is doing in response to their instruction and adjust accordingly.
That is one movement that involves your hamstrings. Now try this and focus!Can't see how you could use the hamstrings to move the com forward.
Hamstrings are used to move the heels towards the butt, similar in function to biceps.
Well, technically the hamstrings will fire in either scenario. To pull your feet back they will concentrically contract (shorten) while the quads will eccentrically contract (lengthen, to decelerate the knee flexion), and to move the com forward via extension it is the opposite--the hamstrings eccentrically contract (to decelerate the knee extension) and the quads will concentrically contract.

Yeah, that's because there is friction between your feet and the floor.That is one movement that involves your hamstrings. Now try this and focus!
Stand on both feet. Now pull your feet backwards. To be able to do this in full control you will need your hamstrings (and glutes and lower abdominals). You see: no flexing, no heels that will move towards your butt. But the hamstrings are working.
But at the same time you upper body will move forward. One and the same movement. Some people realize what to do if you tell them to 'pull their feet back'. They will be able to make this movement. Others respond better to 'move your CoM forward'. Not everyone has enough body awareness to actually feel which muscles they use when they move parts of their body. But after 15 years of intense Pilates training, you will know.

On the snow, without friction, your feet move back.
