Why has no one asked what boot are you using?
This is kind of important since boots are bindings need to be compatible with each other when talking about DIN and A/T norms.  A normal DIN boot will not fit into Dynafit-style binding, and an A/T norm boot is not indemnified with a DIN-only binding.
So, do you plan on buying new boots as well or keeping the boots you currently use?
If you are mainly skiing inbounds, why get a Dynafit-style boot/binding setup?  It will ski fine, but you will not be getting the most out of your $1000+ boot/binding combo.  Go with some sort of frame binding (Atomic Tracker/Salomon Guardian or Marker Duke/Baron).  It will be the better set up for you.
