What do orcas, Grizzly bears and the Kästle MX99 have in common? They’re at the top of the food chain in their respective environments and therefore completely in control and utterly at ease. The MX99 instinctively masters all terrain because it never met any member of the snow family that didn’t cower in its presence. It does not find hard snow to be hard and soft snow, even in its densest, most saturated form, is no match for its Titanal-fueled will power. Like all the Kästle MX models, the new MX99 has no attainable speed limit. You can fire the afterburners until your lips flap, but the MX99 will never lose its sangfroid.
The Kästle BMX105 HP can carve if it must, but carving usually means hard snow, and hard snow isn’t its preferred milieu. The BMX105 HP is nearly the opposite of a carving tool despite being built from the same ingredients, contorting Kästle’s customary wood/glass/Titanal sandwich into a double-rockered baseline with only a hint of sidecut. Tapered tips and tails connected by a straighter sidecut create a platform that planes evenly though deep, uneven snow, but be prepared to exert more effort if you want to initiate a tight line on hard snow. It can get away with liking its turns long and fast because its classic construction ensures that no powder on earth can withstand it.
Considering the reputation of Kästle’s formidable MX84, one might expect the LX85 to be likewise endowed with near-nuclear power. Yet this beauty is no beast, but a gracious cruiser that orders groomers for its main course with off-trail conditions on the side. Its slalomesque turn radius suggests a quick stick, but the slight tip taper and early rise on the LX85 don’t naturally dip into a short turn, allowing the skier to find a languid, GS arc that holds with minimal edge angle. “Stable at speed,” confirms one of the Footloose crew. “It does well with longer radius turns vs. short.”
The RX12 SL is built on traditional bones, with a classic, metal/glass sandwich around a poplar/ash core, to which Kästle adds its special ingredient, the colorful Hollowtech tip, to keep its fully cambered baseline in contact with the snow. A continuous-radius sidecut extends all the way into the tip, so as soon as it’s tipped, it’s engaged. Unfettered by FIS restrictions on sidecut radius, Kästle went tighter, pinching the RX12 SL’s radius down to 12.5m in a 165cm.
That both Kästle RX12’s sit atop our Power rankings proves that our testers prefer the more forgiving branch of the race ski family tree. The RX12 GS behaves less like a true race GS than a narrow-waisted carver. It’s unadorned by any plate or interface except what may come with a given race binding, so it isn’t as tippy as a ski with more standheight. Being closer to the snow gives it a more all-mountain feel and allows the skier to roll gradually to the edge. The absence of extra hardware not only makes the RX12 lighter than category average, it helps to keep it supple and easy to bend.
