Dawcatching reviewed a 163 mm SC, think it was the new one, but not sure. There's a review at Real Skiers. And far as I know from the Stockli site, wider version still has two sheets of metal, same general construction as old, but with the grooves cut into the wood core and filled with syn, same as SX, non-FIS GS, and CX. Have not skied the new one, but would guess it's similar to old in feel, but bit slower edge to edge, bit more versatile about surfaces.
