Replying to Backcountry gear

Hello guys, i'm looking for a new setup for backcountry/touring. I want it to be as light as possible and mostly for tree skiing since i already have a ski for big lines. Kinda thinking about the Atk R14 and the kingpins wheter Din13 or M-Werks but cant really decide.. Whats your thoughts on this one? Not really looking for any other binding. Next question would be: does anyone in here have the new DPS Pagoda Tour 112 and could give me his opinion? I really like the weight and small turning radius. Would be open for any other aki recommendation as long it is over 105 width, lighter than 1600g and has under 17m turning radius. Thanks alot and have a great day!!
