I'm about to mount my Salomon Rocker 2's (184) with this AT Setup:
Black Diamond Fritschi Diamir Freeride Pro Binding -120MM - http://www.backcountry.com/black-diamond-fritschi-diamir-freeride-pro-binding-120mm
I'm a big fan of the Fritschi's and prefer them over the Markers. The DIN goes to 12, I never pop out of my bindings. And the convenience of not having to come out of your binding to go into touring mode is huge. Not only when climbing but it's also very useful when traversing flat sections without skins (especially in powder where it can be pain coming in and out of your binding).
The 120mm brakes will fit the Salomon Rocker 2's 122 underfoot fine.
and these bindings are on sale at Backcountry.com so they cost about the same.
