In reply to Jerry67:
You can pretty much slap on any alpine binder on 'em... Exceptions being the newer Marker Freeride series (Jester and such, as the ski is too narrow).
With your mass, I would suggest getting some higher performance (ie. more metal and higher DIN) binders, like Look P15 or Rossignol FKS 155s.
Unless you plan on doing some ski-touring with 'em (which case you'll also might need to upgrade yer boots..), in this case Diamir somethings or pretty much any of the good tech binders on the market (w/ brakes)... So basically Dynafiddle Radical or Vertical binders.
