There happened to be a Volkl rep at Saddleback that day doing demos. I stopped by and told him how surprised I was that a 105 mm waisted ski could carve so easily. He pointed out that the bindings have a lot to do with it, which was an excellent point. Bindings like the Duke, Baron, and Jester, which were specifically designed for wider skis, are probably a major factor in why 100+ mm skis have become so versatile.
I'd like you or someone to expand on this. Would like to know why a Duke, which is designed for the slack country enthusiast, would help push a 105 mm ski better on hard pack.
