i've owner a handful of pairs but i haven't skied any of their newer models since they left for that season and came back with a new line up. the new models look like they have better build quality from what i've seen in person. i've owned the balances, labs, auburns and the joystick ones. all really fun skis, topsheet quality was the only thing i've always disliked from ski to ski, they got beat up too easily (i think they fixed that with the newer ones). easily worth the pricepoint though, all of them lasted me 2+ seasons which is really all i can ask considering the price and how much i beat my skis up.
i would compare their build quality to that of maybe faction or line. they're not necessarily known for durability like k2 or icelantic or on3p, but they are considerably lighter and generally have a very jibby playful feel. also the balances have a very chargy feel too, they are incredibly reliable for straightlining things because of the stiffness and shape, even though they're a center mounted pow ski. i've always liked their skis and might pick up the new attila pow ski at some point
