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 15.0-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.
A 14.8-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.
Stability & dampness
A full titanal layup gives it a damp, planted build that holds a line through rough snow and rewards a forward, driving stance. At 1,700 g the damping comes without a heavy overall weight.
A full titanal layup gives it a damp, planted build that holds a line through rough snow and rewards a forward, driving stance. At 2,290 g it's a heavy ski built to stay planted and push through chop.
Float & width
At 70 mm it's a narrow, firm-snow ski — quick from edge to edge and built to grip hardpack rather than float. Tip rocker eases turn entry and float; a cambered tail holds the edge through the turn.
At 68 mm it's a narrow, firm-snow ski — quick from edge to edge and built to grip hardpack rather than float.
