These babies are a true one ski quiver. I ski Alta, primarily, so am no stranger to a very wide range of conditions. Untouched waist deep one run after a storm, to sun-affected ice on west facing slopes the next, with everything in between all in the course of an afternoon. The Astris takes it all with ease.
What they are not are a recreational ski. These are a fairly stiff, with some good torsional rigidity, meaning they don't have a lot of 'give.' If you're not careful, they will ski you. That being said, they do have a playful side and will react with good response and 'pop' in the right scenarios. These two elements combined make for a perfect Alta ski (or any Rocky Mountain area, for that matter). Also, for being a stiffer ski, there is enough flex in the nose to float no problem in soft snow. The stiffer flex overall, with the floaty nose and somewhat playful nature makes them shine best in crud and chop, which, let's be honest, is what we all find ourselves in most of the time.
If you are an expert skier and looking for that one ski to replace your beat up multi-ski quiver, the Astris is your top choice.
My skis before these were the Atomic Coax (older twin tip model, about 108mm underfoot) and the Atomic Automatic 117, for some context.
