When linking turns, are you supposed to unweighted both feet, or just the front foot? For ex. Your in a toe side traverse, to do a heels side turn, do I keep the grip on my back toes, while transferring weight to my front heel to initiate a heel side turn? And if so, how soon after putting weight on my front heel do I put pressure on my back heel in a turn?
Same thing toe side.
Also, should weight always be on the front foot, and knees always be bent?
People say to stay low, but when watching other riders, they don't seem to always have their knees bent.
Personally, I think the torsional flex explination is a difficult to translate in to riding for a beginner/intermediate rider because it involves some subtle movements and timing...its a good conceptual but putting it into muscular movements...while dealing with speed anxieties, terrain reading, collision avoiding and etc. is abit much.
There are two basic approaches or focuses to turning...top down (look where ur going) and bottom up (feet and knee movement)...eventually you learn to use both at the same time for efficient riding.
As far as watching other riders...its good to recognize good riders...but a noobie generally does not know what is good riding nor able to see the subtle differences unless specifically pointed out and it also depends on where they are at in their level of progression and thus what is most helpful to pay attention to.
Thus in conclusion...having a good instructor that can readily see your level and see what you need to specifically work on to take you to the next level...and be able to explain and show you in a manner that you can undeerstand and implement.
Also imho...the hill/terrain/snow conditions also play an important factor...learning on ice, packed or pow will have a bit of a different focus. An example, last Saturday on packed pow, I was taking 2 girls who were on day 6, down a ducked rope double black to teach them about steepness and getting them to straight-line bomb some blue runs to teach them about how to manage our terrain traps and riding flats.
