Replying to Powder Specific skis worth it?

Hey so I'm thinking about getting a pair of powder specific skis, I have 108 kartels as my daily drivers (also have 112 steeples for touring, figured might be worth mentioning) and I know they are great in well everything but I had moment night trains a few years ago and I'm thinking of getting something similar to those again but don't know if it's worth it. I've looked at on3p c&d's, moment ghost train/ bibbys, and atomic bent chetlers. Any thoughts? Any input is appreciated :)
