Yikes a ski thread.
Ski-it-again is a great place to look at skis.
Ski length is based on the riders weight and the boat speed, and is published by the ski manufacturer, follow it or if anything go one size up if you tend to go slower or get fatter.
Binding wise, the Wiley's are a good start for most anyone, don't run em too tight, and you seldom hear of any injuries in them.
If you liked your Radars the Radar RS-1 or Strada or whatever its called is another solid option, again not too tight.
