The K2 Disruption MTi Alliance is an awesome choice for advanced and expert ladies who love to spend their time on the groomed and smooth trails on the front side. Looking for race-like performance, but without the race build, skiers who end up on the MTi Alliance are likely strong skiers who value edge grip, precision, stability, and dampness. Built with an Aspen wood core, these skis have the power and pop to propel you down the hill with intent and purpose. With a narrow 72-mm waist, the MTi Alliance has a ton of torsional stiffness right from the start, but K2 adds a couple more aspects to the ski that make it rock-solid and totally stable. The Titanal I-Beam does a lot of the heavy lifting in terms of stability and power, as this metal laminate extends from edge to edge underfoot before tapering to the middle in the tips and tails. This leaves the edges of the ski unburdened by titanal, and makes the ski more approachable and versatile, all the while making it damp and vibration-resistant to the firmest snow that you will be able to find.

On the groomers, these things really light it up. Thanks to the shape, profile, and construction, the K2 Disruption MTi Alliance can lean into a turn and pop you out of it on the back end. True tip to tail camber and taper have a lot to do with this, as we don’t see a whole lot of skis that have this pure non-tapered shape. The result is that you get full edge contact, allowing for a smoother ride and better edge grip throughout the length of the ski. A byproduct of this build is that the skis tend to feel a bit longer, and there’s nothing wrong with that. In the 160 cm length, these skis generate a 14.6-meter turn radius, so they are encroaching on the slalom-side of the equation, and as a result, they prefer to be on edge.

Kristi Brown was on the 153, so quite a bit shorter than she’s used to skiing, but still noted that “for a slalom-style of ski, and with the shorter radius, it definitely skis true to size.” By being able to view this ski through the lens of a slalom racer, Kristi is able to pull some attributes from this ski that don’t really fall into the all-mountain category, so it’s pretty clear that these skis are fairly one-dimensional from Kristi’s view. She scored the ski 5’s out of 5 for stability, playfulness, and forgiveness, with 4’s right on their heels for quickness, maneuverability, torsional stiffness, edge grip, and overall impression. The 1 for flotation and the 2 for versatility are not surprising to say the least. Kristi notes that these skis are “Super fun fast and fiery not for the faint of turning heart. If you are a turn seeker ready to burn and churn your way down the hill - the Disruption is your weapon. Super narrow underfoot at 72w - you either are in great shape or you are getting an immediate leg crusher in turning.” Effort counts in the sport of skiing, and when you get on something like this, it becomes even more apparent.

There’s a lot to like about a strong, hard-charging carving ski that a lot of expert skiers and former racers gravitate to. If you’re looking for that front side ski that’s on the one-dimensional side, you’ll love these skis and their ability to rip through turns like no other.
