I gained a fresh perspective on the Rustler 9 when I had occasion to ski it at Jackson Hole two years ago. It was a lovely day; however, I was anything but: sick, bone-tired, with a tweaked L4/L5 and a gas tank running on fumes. After an undistinguished descent of Rendezvous Bowl, I straggled my way into the serpentine bumps of Bivouac Woods. If not for the Rustler 9’s mercifully soft tip and tail that seemed to match the contours of every cross-hill trough without much guidance from its beleaguered pilot, I might still be there.
Ski buyers always ask at some point in their give-and-take with the salesperson, “How is it in the bumps?” While the flip reply is always, “As good as you are,” in the case of the Rustler 9, the ski actually is well suited to today’s hacked-up mogul formations.
Put in Realskiers’ terms, the pliable Rustler 9 is a Finesse ski while the stouter Brahma 88 is a Power ski. The Brahma 88’s best scores are for performance criteria like carving accuracy and stability at speed; the Rustler 9’s marks reveal a model with a high aptitude for off-trail conditions with a peppy personality that’s easy to manage. It prefers life off-trail where it has the freedom to add a bit of schmear to every turn.
One of my favorite bump skis that wasn’t intended to be a bump ski was the K2 Shreditor 102 (circa 2015). Of course, it couldn’t be as quick a real mogul ski edge to edge, so it did most of its navigation by slarving through the troughs and slinking around the lumpy bits. The new Reckoner 102 is in several respects the same ski, albeit embellished in ways its ancestor was not.
The similarities are hard to miss. The shape of the 184cm is identical save for a tip that’s 3mm wider on the Reckoner, giving it a marginally (.7m) snugger sidecut radius. Both Shreditor and Reckoner rely on braided fibers to control flex and torsion, with the Shreditor using a Triaxial braid of fiberglass and the Reckoner using Spectral Braid spun from carbon. Both vintages use Aspen in the core, although the Shreditor complemented it with featherweight Paulownia while the Reckoner uses Aspen in concert with denser fir. Both have relatively low camber underfoot, use a reinforced sidewall for added resistance to ski-on-ski damage and both, of course, are twin-tips.
What the Reckoner 102 brings to the party that the Shreditor could not is Spectral Braid, a variable-angle braiding technique (Patent Pending). Spectral Braid makes both front and rear rocker zones soft and compliant, helping the Reckoner 102 switch from forward to reverse in a twinkling.
The entire Big Mountain genre owes K2 a debt of gratitude for championing the concept of rocker with such fervor that it was soon adopted as an essential design element for any ski over 100mm underfoot. As an early adopter of double-rockered baselines, K2 has a lot of institutional expertise at making a very wide ski that’s very easy to steer. The Mindbender 108 Ti continues this tradition of simplifying off-trail skiing with just the right balance of baseline, sidecut and flex pattern. One of the Mindbender 108 Ti’s strong suits is its huge ability envelope, which means almost anyone can get on it and have a ball.
It takes only one section of uncut powder to realize that this unsullied canvas is where the Mindbender 108Ti would prefer to display its artistry. Who wouldn’t rather ski unblemished freshies? By afternoon what was once pristine has become a mogul field. Remarkably, its soft, rockered forebody allows the 108Ti to conform to gnarly bumps – I’m looking at you, snowboarders – as if they were only a minor inconvenience. Because it isn’t torsionally rigid throughout, the Mindbender 108Ti doesn’t feel as wide as it measures. In soft snow it feels comfortable enough to be an everyday ski, but that’s asking a lot of a ski that likes powder as much as you do.
K2 has always placed Forgiveness at or near the top of its hierarchy of desirable ski qualities. True to this heritage, the Disruption 82 Ti earned its highest marks for Forgiveness/Ease, which helped make it one of the few Finesse skis in a horde of Power-crazed carvers.
The most obvious reason why the Disruption 82 Ti comes across as easier to ski is its width; at 82mm underfoot, and with a less radical sidecut than most Frontside Power skis, it’s easier to throw into a drift and it won’t buck when introduced to ungroomed terrain.
The less transparent reason pertains to how it’s built: the Ti I-Beam that gives the Disruption 82 Ti its bite is only as wide as its midsection. This gives the edge elsewhere a subtle flexibility that’s ideal for anything but boilerplate or frozen ridges of spring corduroy.
While it’s definitely a carver of the kinder, gentler variety, beneath its easy-going veneer it’s still a trench-digger at heart. The widest model in the Disruption clan, the 82 Ti is predisposed to a medium-radius arc that it can reel off without much effort on the pilot’s part. It stays connected in part because the Ti I-Beam runs tip to tail and in part because its baseline has only a teensy bit of tip rocker that doesn’t prevent the low-to-the-snow shovel from finding the edge at the top of the turn.
K2 completely changed every core model in its 19/20 line, without straying one centimeter from its core values. True, the Mindbenders were built differently than the Pinnacles that preceded them, using all wood cores in their Ti incarnations (saying ta-ta to Nano-tech), and more Titanal in the tail section to increase rear support compared to the passé Pinnacles.
Even though the Mindbender Ti series, of which the 90 Ti is the narrowest, aims for a better class of skier (if you’ll pardon the expression), they’re not so stout they can’t be controlled by adventurous intermediates. The Mindbenders’ Ti Y-Beam construction puts Titanal over the edge in the forebody but moves it away from edge in the tail. This adjusts the skis’ torsional rigidity requirements to create more bite in the forebody and easier release of the tail, without affecting their even, balanced flex longitudinally.
Light and responsive to a gentle hand on the reins, the Mindbender 90 Ti may at first blush feel a tad too loose in the tip to trust at warp speed, but it proves trustworthy if given a chance to run at high rpms. An elevated platform connected to the core by its robust sidewall gives the Mindbender 90 Ti turbo power when rolled on edge. “It turns the way you ask it to and holds with confidence on hardpack,” attests Ward Pyles from Peter Glenn.
