i dont know, they arnt that bad, but compared to some of the better skis out there, not good. they're nice and flexy but you can feel how heavy they are on high jump on's. i had mine for one season, at the start they were pretty poppy, but around march, the pop was gone. now i have domains, and just flexing the two of them beside eachother, you can feel a massive difference. i would look for something else, not skate deck tech for sure
