I personally haven't skied either of these but if I were choosing one, I'd go with the Atris. A buddy of mine works at a shop and sells Black Crows products and is super hyped all the time about the ski. From his point of view, its super stable at mach speeds and has a smooth flex out of the tail to help those larger cliff drops. As well, Black Crows makes an extremely well built product that wont fall apart on you and will be super reliable after beating the crap out of them. ( I have the Venors from a few years back and love them).
If you're looking at a fatter ski as well, the black crows notca is a super sick ski. Reverse camber and highly playful; it lets you make anything really your playground. I believe its 122 underfoot which may be a bit fat for what youre looking for but that fully rockered profile allows you to engage that underfoot edge first allowing for a wide range of smooth turning.
