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 13.3-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.
A 13.6-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.
Stability & dampness
At 1,698 g it carries a moderate, manageable weight underfoot.
A full titanal layup gives it a damp, planted build that holds a line through rough snow and rewards a forward, driving stance. At 1,630 g the damping comes without a heavy overall weight.
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.
At 72 mm it's a narrow, firm-snow ski — quick from edge to edge and built to grip hardpack rather than float. A cambered profile keeps it locked to the snow for grip rather than smear-and-release.
