The Mirus Cor’s rocker profile is also nothing like the majority of 87mm-wide skis on the market. It has deeper rocker lines than any similarly narrow ski I can think of, and its tip and tail rocker lines are basically symmetrical. And that split tail is also basically a true twin.
So we’ve got a shape that’s roughly reminiscent of a slalom ski, paired with the rocker profile of a much wider all-mountain freestyle ski. Interesting.
Flex Pattern
Here’s how we’d characterize the flex pattern of the Mirus Cor:
Tips: 7-6.5
Shovels: 6.5
In Front of Toe Piece: 7-9
Underfoot: 9.5
Behind the Heel Piece: 9-7.5
Tails: 7
The main thing that stands out with the Mirus Cor’s flex pattern is that it’s relatively soft outside of the binding area. The very ends of its tips and tails aren’t actually super soft, but there’s a pretty slow, gradual ramp-up in stiffness as you move from those ends to the middle of the ski. I did the flex pattern numbers after my first day on the ski and I was actually surprised it didn’t feel softer when flexing it by hand — on snow, it feels very easy to bend the majority of the ski.
Sidecut Radius
As we alluded to above, the Mirus Cor has a very tight sidecut radius — Black Crows say that it’s 13 meters across all available lengths of the ski. That’s basically on par with the Line Blade, and a bit tighter than the Armada Stranger. From first glance, it’s pretty obvious that the Mirus Cor is going to want to carve hard and tight, rather than make big, drawn-out arcs.
Mount Point
Another point of differentiation — the Mirus Cor has a recommended mount point that’s only about -3.8 cm from the true center of the ski.
That’s a mount point we’re more used to seeing on park and all-mountain freestyle skis, not narrow carving skis. But, it does fit with the description from Black Crows.
Weight
Similar to — and likely as a result of — the Mirus Cor’s straightforward construction, this ski’s weight isn’t particularly out of the ordinary. Our pair of the 178 cm Mirus Cor came in at about 1817 grams per ski, which is neither extremely heavy nor extremely light for a ski of its size. It’s a bit on the lighter side of things, but it’s got plenty of close company, weight-wise.
For reference, here are a number of our measured weights (per ski in grams) for some notable skis. Keep in mind the length differences to try to keep things apples-to-apples.
