Both are gonna be SUPER durable, Armada makes quality park skis and Line spent 4 years making sure the A-bangs are durable (plus, K2 - which owns LINE - always makes sure their stuff is durable). The afterbang will probably be the more fun ski and slightly better on rails cause it symmetrical (which the thall is not). I love Armada, but I've got a pair of Afterbangs coming my way so I'm gonna say Afterbang.
