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 13.0-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.
A 14.0-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.
Stability & dampness
Built without metal on an aspen veneer, it's lighter and livelier underfoot — easy to release from a turn and quick edge to edge. At 1,560 g it's a genuinely light ski, nimble and easy to move around.
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 1,350 g it's a genuinely light ski, nimble and easy to move around.
Float & width
At 90 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.
At 91 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.
