First, define backcountry for yourself. Everybody has a different definition of what backcountry means to them. After you define what backcountry means to you, or what it is you're trying to access, then your gear choices will become more clear. And the further away from people you go, the easier the choices become.
If you're trying to access the remote backcountry on skis, then I think you'll find that snowshoes are definetely NOT the way to go. For this your very best options are Telemarking and Alpine Touring (also refered as AT or Randonnee).
As a strong skier who doesn't want to relearn how to ski, go AT. And based on what you've said so far in this and your other thread then i think the Fritschi Freerides may be your best option. I haven't been sold on the Naxos yet, this is a brand new binding and I understand it still has a few bugs to be ironed out. And as you're already heard, neither of these bindings are 100% bomber but they're as burley as they make em for AT. For what it's worth, I own the Freerides and the Dynafit TLT bindings. I love both sets of bindings and have never had any trouble with either, but then again I'm super careful with my gear and I'm not a maniac when skiing in remote areas.
