Im 5 foot 110 pounds. Im an advanced regular skier and intermediate in the park. Im looking for a good binding that wil be pretty durable but also light. im currently riding Marker griffons on my k2 extremes and im getting k2 domains. I kinda want to get griffons on my domains too but if i do that i will just take them off of my extremes. So the main question is.......what light weight bindings should i put on my extremes in replacement of my griffons?
