It's good to see the Swix roller skis with NIS binding plates. This is just a sensible thing with so many people on NNN/NIS these days. Note that the Swix roller skis are also drilled for Salomon bindings, so if you're going that way, you just unscrew the NIS plates and screw down the Salomon bindings. No drilling required at all.
