* A flagged radius is the underfoot figure from a multi-radius sidecut, measured differently than a single full-length radius — the positions are not strictly comparable.

Head to head, by character

Each ski's own read, side by side — the same three things that define how it skis.
Turn & shape
A 14.0-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.
A three-radius sidecut blends a shorter radius at the tip and tail with a longer one underfoot, so turn shape changes with how hard the ski is driven — tighter entry, longer and steadier through the arc.
Stability & dampness
Built without metal, it's lighter and livelier underfoot — easy to release from a turn and quick edge to edge. At 1,675 g it stays light and maneuverable.
A partial titanal frame stiffens the core — targeted dampening that settles the ski without the full weight of a sheet, keeping more life in the tips and tails. At 1,670 g it stays maneuverable underfoot.
Float & width
At 84 mm it's an all-rounder leaning toward firm snow — enough width for soft conditions, still quick on edge. Rocker at tip and tail lets it smear and release easily, while the camber underfoot keeps an edge.

* The two skis may measure turn radius differently. A multi-radius sidecut publishes a separate radius per section; the figure shown is the underfoot radius, which reads tighter than the ski's real all-mountain turn shape. We show each as published rather than forcing a false match.
