Here is my 2c of the group individuals on a horribly bad worn out natural bump run.
This guy is one of the less skilled skiers in the group but he has great potential because he looks athletic. His problem is his lacking basics. He probably never took a ski lesson back when he should have. Also, two from this group could not carve, he is one of them. He has a very strong up and down motion on a groomer. Up-unweighting his turn initiations. His next move is to pivot his skis and rotate into the turn. This move is ingrained and one of the reasons he cant find the carve. He depends on two skidding skis. In the bumps the consequence is that his extension takes place when he is on a bump. This puts him in the air. He tries to fix it by absorbing the moguls and pivoting the skis but that does not work well since his speed accelerates. Also, his hands are to my taste too far in front putting his butt back too far. It looks a bit like how the bump pros use their arms. Not my cup of tea. Good solid stance.
This guy shares the exact same symptoms as the previous skier. Up-unweighting pattern not in sync with the bumps. He skis well on a groomer and carves nicely but in the bumps he is struggling. He picks up speed and gets thrown in the back seat. Strong athletic skier with great potential.
This is the most fun to watch skier and also the one with the most solid skiing on a groomer of the group. Nice short turns and nice carving. Not bad. Here in the bumps he fails the same way the two previous skiers. Up-unweighing not working for him. Instead he flexes and pivots and skids massively. Picks up speed and gets thrown in the back seat. On a groomer he shaped his short turns fine. More of that here. The line is also too fast. Just like the guys before him. If you stay in between the bumps you pick up too much speed since the moguls are spaced too far apart. They should ski more over the bumps. Now they are avoiding them. Like they were their enemies when they in fact are their best friends. Here is what they should do. In this case it would have meant a totally opposite perpendicular line.
To the left in read the line he skis. In blue a slightly tighter and rounder line making use of the soft snow on the uphill side of the bumps. To the right in green an optional line. You need to find soft snow to dig your ski tips into. And there is plenty of it around so don't skid around on hard icy patches.
Strong athletic skier. Skis well on a groomer. Carves well. Is to stiff in his upper body though. Little upper lower body separation. In the bumps he is looking surprisingly good. Check out his line selection. He is finding that soft snow to turn on and to crash through. He even flexes nicely in some places even though when he crashes he failed to do so. This slope doesn't look very steep but check out how he glides down hill. Its steep. Well done.
She doesn't belong in the group and cant really ski well even on a groomer. Cant carve. But she is putting in a good effort. And even skiing down this slope is an achievement to be proud of. We should not put her down. She is doing fine. Just need s to work on basic things. First thing she should do is close her stance width down. It doesn't work on a groomer and it does certainly not work here in the bumps. You need to be more compact. Keep your skis tracking closer together because even a few cm to each side the terrain can be totally different. Then she should work on flexing and extending because she is very stiff in her legs. Proper line selection would take care of the rest.
