Marsound, reference to "+1.5 cm" comes from pre-defined settings on the Head Railflex Speedrail bindings. These bindings slide on a rail and can be fixed on it in one of three standard positions. There is a screw in the middle of the binding, between the heel and the toe pieces, and next to the cap which locks the toe and heel sliders in place. This screw helds the bindings on the rail. One removes the screw and slides the bindings as a whole along the rail to one of the three positions determined by pre-drilled holes which this srew can go into. These positions are labelled on the rail as "+15", "0", and "-15". The indicator which shows these numbers is right next to the screw. It is not on the ski itself but on the bindings. If you have a different type of bindings, your only option is to move toe and heel pieces in the same direction by the same amount. The "+15 mm" position is not a magic number which comes from high tech considerations. It is simply a pre-defined setting of the Head rail bindings. There is no reason not to try +20 mm or +25 mm if you are in a testing mood, but people rarely go beyond the beaten path. If you decide to test values greater than +1.5 cm, let us know how the ski feels with those positions!
