Snow and ice can accumulate in the tie length adjustment of the EA universal bandage, especially if you are wearing stiff footwear that causes a lot of movement with each step. While it may be difficult to prevent snow accumulation in some snow conditions, using a silicone spray can help prevent snow from sticking to the bandage and also reduce any possible creaking noise.
As for using other bindings, it is possible to install bindings such as the NNN BC binding on Skinbased skis, but it is important to carefully follow the installation instructions for the specific binding and to check the appropriate screw length. The back of Skinbased skis has a sticker that indicates the location of the NN75 point screw, and the "pin line" of the ski is 2.5 cm from this point towards the heel. For example, on a KAR 147 ski, the NN75 is located 82 cm from the base to the tip and the "pin line" is at 79.5 cm. The NNN BC binding has a marked pin line that should be placed at this point. It is still recommended to use the EA universal binding for Skinbased skiing as it is designed specifically for this purpose and provides optimal performance.
