Hybrid bindings vs alpine bindings?

I bought a dedicated pair of powders ski for the upcoming season and I need to get them mounted. I live in the mountain west and, to date, have only skied in the resorts. However, I am wonder if I should opt for a hybrid binding should I decide to start getting into back county skiing. But I've only been skiing for a few years, so I'm just not that familiar with hybrid bindings or whether this idea makes sense. Any advice?
