I was looking at used crud skis and found one that looks like a bargain, but I would prefer to put a Marker Piston 1200 on them if I buy them. How would I know beforehand if the skis could be remounted with the Markers? Is it a matter of the different binding's screw patterns or a need to positiont he new bindings forewards or backwards on the skis? Also, does anyone know the brake width for Marker Piston bindings? Thans for your advice.
