U may know already that Salomon's topsheets are double marked underfoot 1) progressive and 2) classic-meaning more carving or all mtn behavior.Go to the Salomon website
http://www.salomonfreeski.com/others/ski/skis/freeski/suspect.html and run the video (Sammy Carlson) and PAUSE it right when it goes over the boot/binding. That ski looks "progressive mount" or forward. U can also pick any ski and ZOOM the picture to see the 2 mounting lines.
http://www.salomonfreeski.com/others/ski/skis/freeski/dumont.html U can do the same with Simon Dumont video.. I think these 2 guys are influential enough. I think they were showing their own skis... Maybe this helps
