It used to be that when testers jumped on a K2, they expected a loosey-goosey, playful ski that was fun to tool around on, but not the best for slicing up groomers. But the new Disruption MTi Alliance is not that kind of K2.
Featuring K2’s Dark Matter Damping technology and a sheet of Titanal that runs throughout the length of the ski, the K2 Disruption MTi Alliance didn’t come to play around. Add to that beefy construction K2’s Speed Rocker profile with zero rocker in the tail and just a smidge up front in the tip, and this ski was designed to stick to snow like white on rice.
Our testers loved this quality for frontside carving, and ranked the K2 MTi Alliance high in Stability at Speed and Hard-Snow Integrity because of it. But they also raved about how responsive and quick this ski is from edge to edge thanks to its narrow little waist.
“Feels racey,” comments tester Stephanie Humes. “It’s quick, snappy, and aggressive. It can make smeary turns, but it wants to make them fast.”
Because the K2 MTi Alliance has a propensity for getting up on edge, testers noted it would make a great carving ski for ladies who need a little help in the edging department. Says tester Katie Ryan: “It’s super easy to tip on edge and is made for ladies who don’t want to work so hard for beautiful slalom turns on groomers. Performs well even at high speeds. It’s not as burly as some in this category, but still has the same capabilities.”
It may be quick, but don’t mistake quickness for playfulness. K2’s Dark Matter Damping does the trick for smoothing out bumps and giving skiers a solid platform underfoot, but it also saps some of the energy from these skis. Testers who gravitate towards skis with bigger personalities were somewhat disappointed with the MTi Alliance’s rebound in and out of turns; but they acknowledged that what it lacks in vivaciousness it makes up for in stability.
“Quite stable without being heavy,” says tester Robin Barnes. “Performed beautifully in short and long turns. I could push it or back off and it responded equally well. An ideal ski for the frontside gal who loves early morning corduroy.”
