Replying to Line Chronic, Armada Alpha 1 or El Ray

So, my Atomic Punx 2011 skis are getting pretty beat up, and it's soon time to get new skis. Now I've narrowed my choice down to these three skis; Line chronic 2009-2010 in 171, Armada Alpha 1 176 or Armada El Ray 171. I'm looking for a decently light ski, but most importantly the most durable of the three. By the way I'm 5' 10" and weigh 130 pounds. I ski mostly rails, some jumps (70/30).

Oh, and k+ for helpful replies.
