Week 5 update... I think I had an epiphany recently. Delving into video analysis, talking with my instructor, and putting a concept together about that back leg. Please correct me if I'm wrong, but my thought is that the back leg is like a rudder. We want to swing it out (externally rotate) and drive the knee down towards the toe side turn. Then the leg swings inboard (internally rotates) transitioning into heel side.
Practicing this, I think it began helping me begin to resemble the position I see the great riders using on their heel sides - and avoiding the "squatty potty." So, I've got an hour or two working on this refinement of my back leg, captured in the week 5 video. I plan to keep working on this.
However, my instructor commented that I'm using too much upper body to tip into my toe sides, and not enough lower body. We worked on this and the improvement seemed to help me get on toe side edge earlier, higher in the turn. I also practiced trying to pull myself down to the board when transitioning from heel to toe. A retraction if I'm correct. I'd like to refine this action too.
I'm having a ton of fun with learning to carve. The performance even riding an old board (Burton Cruiser) for me at least is already much greater than I accomplished after 30+ years of skiing.
In summary, I plan to work on: using back leg more actively, tip to toe side with legs, less upper body lean and get on edge earlier. Also should note that I'm riding steeper slopes now than the video, which seems to make some things easier, but some things harder - or really just helps identify areas to improve.
Angles were 33/24. I upped the rear binding to 27 yesterday.
Edit: I think ideally, both legs should be rotating a bit (not just back leg) and knees remain about the same distance apart - no pinching (?).
