I skied a pair of Rossignol Soul 7's last Sunday and was smitten. With the Griffon demo bindings, the whole rig was remarkably light compared to the Kastles that I usually shlep around. I like having the flexibility to move the bindings laterally which is why I have invested in the VIST plates system which I have on several pairs of skis. For those unfamiliar, this is what it looks like:
The black plastic piece is a 4mm shim that goes under the toe. It works well for me.
While the plate does not weigh much, and adds no obvious stiffness to the ski, the bindings are pretty heavy. Is the weight of these bindings going to affect the responsiveness of this ski, which is one of its endearing qualities? I know I could get a pair of Marker demo bindings, but they cost considerably more than the VIST plate, and I like the idea of one set of bindings for several set of skis.
