| Skier | Carve radius at 30° / 45° / 60° edge | Edge hold, groomed | Edge hold, ice | Float, powder |
|---|---|---|---|---|
| 70 kg | 13.9 / 11.3 / 8 m | Holds well (100%) | On the limit (71%) | Sinks (17%) |
| 90 kg | 13.9 / 11.3 / 8 m | Holds well (100%) | On the limit (68%) | Sinks (16%) |

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 Q4 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 (41%)
- Intermediate: on the limit (70%), assumed level
- Advanced: holds well (95%)
- Expert: holds well (100%)
Float
In soft snow- First-timer: sinks (12%)
- Beginner: sinks (13%)
- Intermediate: sinks (14%), assumed level
- Advanced: sinks (15%)
- Expert: sinks (16%)
Ease
How forgiving it is- First-timer: hard (0%)
- Beginner: hard (28%)
- Intermediate: easy (80%), assumed level
- Advanced: easy (100%)
- Expert: easy (100%)
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.
