| Skier | Carve radius at 30° / 45° / 60° edge | Edge hold, groomed | Edge hold, ice | Float, powder |
|---|---|---|---|---|
| 70 kg | 16.5 / 13.4 / 9.5 m | Holds well (100%) | On the limit (64%) | Floats well (88%) |
| 90 kg | 16.5 / 13.4 / 9.5 m | Holds well (97%) | Slides (59%) | Floats well (76%) |
| 110 kg | 16.5 / 13.4 / 9.5 m | Holds well (95%) | Slides (56%) | Some float (68%) |
These are the model’s numbers, not measurements. Carve radius comes from the sidecut, so it does not change with weight; edge hold and float do. Flex and camber are our estimates (see “What the model uses” below).

Our model, run with working assumptions about how each level skis (edge angle, speed, how much weight reaches the edge). Not measurements. The marked cell assumes an intermediate skier; compare with your own details to see your own level.
