Haven't got to test the durability, but I've heard nothing but good things about CoreUPT as of late. They seem to have a uniform mid-range flex throughout. My 171s on my bathroom scale read around 6.5 lbs for the pair (3kg). Hopefully this helps you guys.
Haven't got to riding my candide yard 09/10s yet but i can tell you they're light as fuck, medium stiff, massive amounts of camber and the tips have quite a lot of rise on them too.
I had around 7 days on my pair last season, as they were only used for pre-season. Great ski, durable, pretty fun for me, and they held up to rocks fairly well. Only thing i would say is wax them. Then they are fast. And yes they are LIGHT.
my buddy has em says they are the best ski he has owned, nice even flex that is soft enough for butters but stiff enough for jumps.Really reallly durable ski, he has skied hard on them roughly 20 days of park skiing and they still look brand new its nuts cause they dont even have that many chips on the side of the topsheet from mute grabs etc. Also his edges are mint condition no cracks or any of that bull shit.They are a surprisingly light ski with a very low swing weight u can wipe em around prettty good. They lastly have quite a bit of camber and alot of pop to them.
bump! i want to get the 171's, do you guys think that would be too big for me? im about 5'6 and still growing and a little over 130 pounds but my dads only 5'7 5'8 so i doubt i'll be much taller than that
coreupt is known to measure long so the 171 will be about 168. the really exaggerated tips on each of their skis makes them ski shorter so you have to be aware of that. but that size would fit you fine. Coreupt is legit and their customer service is rated high since you can only buy them online they try to make durable skis that will not have problems that is why they are really durable.
