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 Atomic Redster S9 FIS J-RP³ at 138 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, 138 cm- First-timer: slides (19%)
- Beginner: slides (41%)
- Intermediate: on the limit (70%), assumed level
- Advanced: holds well (95%)
- Expert: holds well (100%)
Float
In soft snow- First-timer: sinks (8%)
- Beginner: sinks (9%)
- Intermediate: sinks (9%), assumed level
- Advanced: sinks (10%)
- Expert: sinks (11%)
Ease
How forgiving it is- First-timer: hard (0%)
- Beginner: hard (0%)
- Intermediate: hard (0%), assumed level
- Advanced: hard (0%)
- Expert: hard (30%)
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.
