Replying to 2018 Line Chronic Vs. K2 Poacher

Looking for a ski that will spend about 80% of its life in the park. I do a good balance of rails and jumps, but nothing huge. I’m a fairly traditional park skier (not a crazy buttery skier) but I would like something that butters well. Weight isn’t a huge priority but I would prefer a lower swing-weight. I would love to get 2-3 seasons out of my next park skis so durability is key. I’m 5’10”, 156 lbs, prob gonna get something in the 170-179 range. Can anyone vouch for either of these? I live on the ice coast so they don’t have to be great “mountain” skis and I already own powder skis so that is completely out of the picture. Thanks!
