if there dulled down more, they will be extra surfy and buttery in the pow, better for like pow jibbing. however, i like to keep mine sharper because i ski more big mountain and i like to slash spines and hold an edge in the pow. so it really depends on what you want to be skiing, if your just playin down in the trees it would be more fun (imo) to have duller, more rounded edges to smear on etc, if ur gonna be killin' lines up in the alpine, i would keep em pretty sharp.
