Really good review here.
"A large factor in how well they perform out of the park is Tom's mount point choice. His preferred choice for the ski is -3cm from center and this is where I skied them for the majority of the test. For a park ski this may sound strange not to just center, but this is a directional ski so is not optimized to be centered. I did try them centered in the park and yes they did feel a bit more fun on jibs and rails but the carving performance was affected. Yes center may be the go too for most of NS but there is something to be said for mounting a ski closer to where the recommended line is, and hey who are we to argue with Wallisch."
