I have ridden a pair of the 177 flat camber version of the AoS last season here in central New York. I skied about 70% rails, 30% jumps for 50 days exactly.
I LOVED these skis, snappy, responsive, light and overall, a lot of fun! These performed exceptionally on rails because of their weight. Flat camber also makes surface swaps pretty slick, too. I also felt like I could load up on them and jump over just about anything.
For jumps, I never really had an issue with them. A little bit more stiffness would have been favorable for my body type (5' 11'' 200 lbs), but I feel like for a more averaged sized skier, these would be perfect. However, I never really had an opportunity to push these skis on jumps bigger than 50ft because of such weak snowfall/snowmaking last season. I buttered these around quite frequently and loved every minute of it.
In terms of build quality, I was able to enjoy a lively ride for the first 35 days. The race bases were AWESOME too, I never had to hike as high as my friends and could clear things that no one else could on a regular basis. I had easily over 30 hairline to full sized edge cracks on them that didn't effect performance. By day 36 or so, my sidewalls started to blow out and the topsheet separated from the sidewalls between my toe pieces and heel pieces. Here, I also started to feel the flex break down to become progressively floppier. Days 45-49 I noticed a fracture in the sidewall of my right ski right at core center. On day 50, last Sunday, I blew out my sidewall to the point of core exposure between my toe/heel, being about 3mm deep measuring from the edge inward. I didn't really feel like I could lock out the edge and get the pressure I needed to push around front 450's on a higher mellow down rail. The ones I did get around, I washed out to my back because the tails got to be like a wet noodle.
If you're not as concerned about riding them as long as I did and are looking for a sick ride with exceptional performance, I would definitely recommend you getting them!
