| Skier | Carve radius at 30° / 45° / 60° edge | Edge hold, groomed | Edge hold, ice | Float, powder |
|---|---|---|---|---|
| 70 kg | 14.7 / 12 / 8.5 m | Holds well (100%) | On the limit (66%) | Some float (55%) |
| 90 kg | 14.7 / 12 / 8.5 m | Holds well (99%) | On the limit (62%) | Some float (48%) |
| 110 kg | 14.7 / 12 / 8.5 m | Holds well (97%) | Slides (59%) | Sinks (44%) |
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).
By ability
The Extrem Project 91 at 177 cm for a 90 kg skier on groomed snow. Reviewers are mostly experts, so read the left of each band for what most skiers get.
Edge hold
On firm snow, 177 cm- First-timer: slides (19%)
- Beginner: slides (40%)
- Intermediate: on the limit (69%), assumed level
- Advanced: holds well (94%)
- Expert: holds well (99%)
Float
In soft snow- First-timer: sinks (37%)
- Beginner: sinks (39%)
- Intermediate: sinks (41%), assumed level
- Advanced: some float (45%)
- Expert: some float (48%)
Ease
How forgiving it is- First-timer: hard (0%)
- Beginner: manageable (65%)
- Intermediate: easy (100%), assumed level
- Advanced: easy (100%)
- Expert: easy (90%)
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.
