The Mirus Cor is Black Crows' piste-side oddball: slalom-like in turn shape, freestyle in attitude. The construction story lives in the description above; this review is about evidence and boundaries. For 26/27 the ski is a carryover — same style number, same geometry, same per-size weights, and no update language in the official 26/27 materials — so 25/26 test evidence applies to this year's ski.

On snow the Mirus Cor does what the geometry promises. PTO's in-house reviewer, an instructor, ran the identical 25/26 ski for three seasons at Mt. Hood: turns fall in on their own, switch and butters come naturally off the forward mount — about -3.5cm from true center per the independent test's spec sheet, matching PTO's own measurement — and the ski stays forgiving when your legs are done. The short radius pays off in bumps and trees as much as on corduroy, and the independent test read the character the same way: a playful, quick, short-radius carver.

The limits repeat across sources too. Neither PTO's three seasons nor the independent test treats it as a powder ski — at 87mm with a soft middle, PTO puts the float ceiling around six inches of fresh, and the swallowtail does not change that. Pointed through chopped snow it gets deflected, and on boilerplate ice the edge grip is merely OK; the single titanal plate does not buy race-carver bite. Where sources genuinely split is how much that matters: the independent test frames it as a conditions-dependent quiver ski for advanced and expert skiers, while PTO ran it as an everyday intermediate-to-expert Mt. Hood ski. Both agree on the weaknesses; the disagreement is about how big a slice of your skiing the strengths cover.

Within the line, the new-for-26/27 Vena Cor changes the conversation: a 100mm sibling that Black Crows itself pitches as 'a ski that does everything, but better' and an independent preview calls a riff on the Mirus Cor with a matching swallow tail — the pick if you want this DNA with real soft-snow range, at the same $999. Next to it, the Mirus Cor stays the sharper, quicker piste tool. The Octo (84mm, $949) — 'Mirus Cor's younger cousin' in Black Crows' own words — is the closest piste-play alternative in the line; the Serpo (93mm, $999) is the conventional, non-swallowtail piste-plus ski; the Camox (97mm, $849) is the all-terrain daily driver.

Sizing runs from 160.1 up to 184.2cm across five lengths, and Black Crows' official guidance is to ski it short — pick the shorter of the two lengths you sit between. MSRP is $999, and the ski is sold flat — the binding is a separate purchase, and we mount it and settle the length question at the shop.
