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 16.0-meter radius sits in the all-purpose range — turn shapes that shorten up or open out without committing to either; a moderate tip taper keeps turn entry easy while the shovel still engages.
A 16.6-meter radius covers versatile, all-purpose turn shapes; a generous tip taper loosens turn entry and lets the shovel pivot and smear when you want it looser.
Stability & dampness
Built without metal on a paulownia wood core, it's lighter and livelier underfoot — easy to release from a turn and quick edge to edge. At 1,400 g it's a genuinely light ski, nimble and easy to move around.
A Y-shaped titanal beam runs through the core — targeted dampening that settles the ski without the full weight of a sheet, keeping more life in the tips and tails. At 2,003 g there's real mass behind it.
Float & width
At 90 mm it's a balanced all-mountain width — real float for soft snow without giving up much hardpack quickness. Rocker at tip and tail lets it smear and release easily, while the camber underfoot keeps an edge.
At 89 mm it's a balanced all-mountain width — real float for soft snow without giving up much hardpack quickness. Tip rocker eases turn entry and float; a cambered tail holds the edge through the turn.
