The K2 Disruption 81 Ti Alliance is an amazing choice for ladies who love to carve deep trenches on the frontside of the mountain. Built with an aspen veneer wood core, these skis have a good deal of power and energy, and this allows the ski to be energetic, strong, stable, and precise all at the same time. The big thing with these skis is the titanal I-Beam that does a lot of the heavy lifting. While a lot of other skis have a full (or two) sheet of metal for dampness and power, K2 gets away with this partial laminate, and it makes a lot of sense, especially since this ski doesn’t have the racing heritage of some of the other big-name front side carvers. This one is capable and willing to stand on its own. The I-Beam has a lot of power, especially underfoot, as the full-width metal laminate tapers to the central spine through the forebody and into the tail. This keeps the ski stable and damp while the edges of the skis (that are unencumbered by the metal) are easier to get up on edge and release the turn on the back side. Dark Matter Damping is found in the tips and tails to make up for some of the loss of metal, and this polymer makes the ski feel like a much higher-end product for sure.

Allison Kozar was on the 160, and notes that it skis true to size. She scored the ski 4’s out of 5 for stability, quickness, maneuverability, torsional stiffness, edge hold, versatility, and overall impression. For something that’s 81 mm underfoot, these are some impressively high scores that go a long way in helping skiers make a difference in their carving game. Not only do you get this superior carving ski, but you also get something that can do a lot of things at the same time. She calls the ski “Nice and solid for firm days and deep carving trenches.” That extra width does help quite a bit with making the ski get deeper in the corduroy, and supplying a better balance point for skiers who like the feel of the non-race ski as a better choice to use in a carving application.

Lauren Lepage had similar scores and a similar experience on her 160 cm test length ski, noting that it skis true to size, and scoring it 4’s out of 5 for stability, quickness, maneuverability, playfulness, forgiveness, and overall impression. For a ski of this shape to be garnering scores like this from our two testers is pretty impressive, and we’re all about it. Lauren notes that “Overall, it’s a fun ski for firm groomers/average east coast day on the hill. A great ski for someone looking for an upgrade, an impressive ski without breaking the bank!” We definitely get a lot of those conditions here in Vermont, so having that ski that’s appropriate for such things is a huge benefit. Like we say most of the time, you should be buying skis for the conditions and terrain that you actually ski, not those that you want to ski. For most skiers, something in the low to mid-80's underfoot for groomers is going to take up about 80-90 percent of their entire ski experience.


Advanced and expert skiers will be able to get the best performance out of these skis, mostly because they are on the heavier side, and those more skilled skiers will know how to better use that weight as an advantage. Not the best for those quick, off-piste turns, but very strong in a carved turn at speed, the K2 Disruption 81 Ti Alliance is a fantastic choice for ladies who love the art of the carved turn.
