That's nice strong skiing Bwpa. Looks like you were letting them run and having fun. Very athletic, good balance, and good upper and lower body separation laterally showing good angulation. It was primarily a demonstration of push the feet away from the body, slide, and slam though. I would like to have seen you utilize more “steering”
of the feet and legs which would get you a rounder turn shape, which would show up as separation of the upper and lower body with femur rotation. Letting the skis move away from you as you tip and steer them onto edge, and continue to steer them through the turn. This will help eliminate the push of the feet away from body and force you to keep the pivot point more centered on the ski. Tactically this should allow you to keep your skis away from the ice patches longer and in the soft snow longer. This will give you the ability to manage the pressure higher in the turn, turning the slide in the turn to a skidded turn and greatly reduce the slam at the end of the slide. Tactically skiing the terrain instead of letting the terrain ski you. Giving you more options with regard to turn shape, size, and where you can turn.
I didn't see any major issues with pole timing so much as the pole being used as a crutch to maintain balance and to help manage the big pressure from the slam. I know this routine all too well myself. So in the direction of pole usage, try a longer duration more deliberate swing, but at the same time try keeping your arms and hands very “soft
” and “supple
” throughout the swing and touch. Soft enough that you won't find any real support from them just directional input and timing cues. Adding more deliberate duration to your swing should help in adding duration to your steering and pressure movements.
Pierre's advice of skiing this terrain without poles would also be good task as well. Off groom black terrain without poles is one of our level III tasks. All in all though good strong skiing.
