I have not skied the Walls, but I skied the Karmas all last season, so I can tell ya what I think about those. I live on the East Coast, and not the strong I'm park, but still it ski it a lot for background info. The first time you ski on them you immediately notice how nice they are carving. I've never raced so I couldn't compare it to a race ski, but I'm guessing it would be similar a feeling. They just feel like they bit into the snow and are much smoother when you carve. In park they are awesome too. Took me a few runs to get us to them, but now I love them. They are amazing in powder for me too. They float really nicely, and handle well between tight trees. However they are pretty stiff, but I don't mind that too much. Makes it hard for in moguls, but I'm not too good at them anyways.
