Just bought a quasi new pair of Fischer RC4 WC GS skis from a fellow bear. They were previously mounted for Look PX bindings with a 317 mm BSL.
My own BSL is 306 mm. I have two binding options and three solutions:
1- Used Salomon 900S Carbon bindings (no longer indemnified, but in very good condition). I have the mounting template, but the front screw holes for the heel piece would have to be drilled where the mounting screws for the rear half of the race plate are located. Also, the existing screw holes for the toe piece would interfere with the new holes for the Salomon toe piece. The solution appears to mount it about 8 mm back of the line. How much will that affect the ski's feel and performance?
2. Solution #2 is to mount a Look PX 12 Race binding. It looks like I will have to use the old set of screw holes, and move the heel piece forward 12mm, or alternatively, drill new holes 11 mm forward of the existing holes. Either way, the boot center would be 5.5 mm forward of the line.
Of these two options, which one is the best or least problematic? Would you rather have the binding mounted slightly forward or back of the line?
3. I am also thinking of filling in the existing holes in the race plate with Epoxy Steel, and redrilling for the PX 12. Would this hold the screws properly, if there is partial interference with the old screw holes (new hole center would be 5.5 mm from center of existing holes, hence partial overlap, since holes are 3.5 mm diameter.?
