I am curious, how can one conclude from a short video that a skier lacks versatility? Wouldn't reaching that conclusion require observing the skier for a longer period of time and skiing in varied conditions?
The question was (from someone other than you) what can Max do to be a better skier?
The answer was "to be more open minded"
You asked me to elaborate and my response was to your comment about ILE not working for you and then pretty much dismissed the need for the movement or that it must not be important for SL skiing
I did not elaborate on your skiing as most of the problems I see have been addressed. You are a good skier, no doubt about that, but from what I see it lacks the versatility of an elite skier. Hence my comment be more open minded. learn the skills and add them to your bag of tricks. They will all make you a better skier.. even wedge turns and hop turns may come in handy from time to time.. To be a great SL skier or GS skier, you will not always be on groomed or race smooth courses. Ruts, marbles, reverse crowns, drop away turns, powder in the course, etc will be found in most race courses and the ability to adapt to them by what ever means you can are all good skills. Even if they are not part of the primary movements.
