Replying to Inbounds touring binding

I'm looking for a touring binding, that has the ability to handle long days inbounds skiing. For patrolling this year, I'm building up a dedicated pair of skis. I need a touring binding (for out of area rescues) that has the ability *durability* to handle days of inbounds skiing. I'm not looking for a frame binding (Guardian, Duke) but a tech binding.

I've narrowed it down to the Kingpin, Beast, or G3 Ion. Does anyone have an opinion on any of those? or any recommendations of your own?
