There have been some small changes to the ski for 2016, the rocker profile has been smoothed and there has also been an increase in camber from 1mm to 2mm. Not enough to warrant a full revisiting of the ski but they do make a difference.
The increased camber makes the ski slightly more stable, and as a tradeoff the ski requires that little bit more effort to butter. They are also slightly more poppy than before which is no bad thing and the performance while carving has improved.
I said in my In Depth review of the 2015 skis that the ski is more or less the perfect ski for how I ski. Revisiting it having skied a handful more skis in the same bracket, I'd still say these are probably the best performing overall of the jibby all mountain skis on the market. Stiff enough to ski properly, yet just about soft enough to play on (given my massive 140lbs of weight), they really will do it all. And they are beautifully built to boot.
However for my personal tastes, bear in mind my weight, I'd like them to be softer when I'm skiing park. As a result I've ended up spending most of my time on what is in many ways this ski's little brother, the Faction Prodigy, which I will be reviewing In Depth in the coming weeks!
