Just picked up my new Volkl Kendos 170 from having Marker Kendos mounted on them.Everything look great! However, I noticed that the rear mounting plates are not completely flush to the ski. They are flush on both ends of the rear plates, but there appears to be a very small gap <1mm in the center of the plate on each one. Is this normal? I just want to make sure that this wont be an issue of them loosening on me down the road. Both of the bindings feel rock solid to the ski.
