@GlenFlint the dynafit skis you linked to are more of a backcountry touring ski. They lack any traction pattern in the kick zone underfoot, so if you were to use them for XC you'd have to apply a kick wax. For a waxless XC ski, REI carries the rossignol bc 100. These are wide (80mm) underfoot but completely manageable with NNN BC bindings.
If you want something that is slightly smaller underfoot the Alpina Discovery 68 or Salomon Escape 68 are great options.
