Last year, I bought a pair of 169 public enemies. The bindings are set at the 'mid-sole' indicator on the ski. I want to move them forward, a lot forward. This is because they're so hard to ride/land switch with how they are set. However, I think if I set them more forward then they won't seem like a long enough ski. So i'm thinking about getting them in a 179, and mounting them in the center of the ski. Any ideas or opinions?
