If a skier has a strong preference for mounting the bindings forward or back the skis can always be re-drilled and the rail-flex plate repositioned.
The fact that you can't reposition on the fly in 15mm increments doesn't mean you'd have to redrill to reposition. You can still remove the toe/heel/band assembly and reposition the toe and heel on the band.
For instance, if you have a 370mm BSL and want to move back 1cm, you'd position the toe as if you were mounting for 360mm BSL, and the heel as if you were mounting for 380mm.
It's not as convenient as the single screw slide with the shorter band, but it's certainly easier, cheaper, and better for the skis than a redrill.
