Front Binding Position on S2

[JAS]

I'm on a S2 67.5 and have been skiing @ stock. Now that water has warmed from 54 to 80 I'm narrow on offside (early turn). Horton was riding considerably back during his review of the S2 and I'm going to head in that direction. My question is "what is the feel (characteristics) that you guys experience, when you jump on a ski, and immediately know the front binding needs to go back, or needs to go forward?

Binding movement can be sort of radical. I guess I stumbled onto my settings. I found the ski was unstable at apex with the bindings stock. As I moved back the finish got more stable. I am still riding the ski with those exact settings.
