Replying to Salomon sth 14 driver vs. Marker griffon

Hey all,

I'm 6' 1" , weigh 170lbs. and will be purchasing Armada AR7 this year.  I cant decide which binding to get though, I ski mostly park but like to take advantage of a good pow day aswell. I want to buy last years version of whichever binding I choose. I'm guessing the salomon will be more durable but heavier, and the marker is plastic so less durable but lighter. I want the binding that would be better for mostly park. What do you guys think??
