Replying to 2014 k2 domains and line chronic opinions??

So I really wanna buy a set of skis but I'm torn between k2 2014 domains And 2016 Line chronics I want a very durable ski and I can't go too expensive. I'm leaning toward the domains because of durability and price but I'm worried that they will be too heavy. Does anyone have any experience with either that they can share. I ride mostly park but also will ride all mountain. I am getting into rails and jumps and and looking for it to be a long term ski for multiple seasons. I weigh 155 and am 5'8 if that helps. Also what length should I get which would be short enough to spin but also butter. Sry for the lots of questions but I need some input
