Also thinking, what happens if you get tipped in a bit too far and need to adjust, how do you do this? Unless you are on supershaped skis this could be troublesome. Remember how, unlike contemporary shaped skis, we needed to blend the amount of forward tip leverage with the amount of lateral edge angle to get a ski to carve well. This movement created a certain torque on the ski, and though the classic amounts of tip pressure are no longer necessary, some is still present.
This may be where the edge and pressure purist who dismiss any need for rotary input would be a bit surprised at the results of Ghost's "lazy susan" test? I think we would discover, though their rotary input may be unconscious to them, it is not so passive as they have come to believe?
