I'm a SN 100 owner and do like them on the groomers (UT skier, so softer snow, even on groomers). My initial reaction to your question is that you may want a ski that is more different from your Rossis. Something that you can really rail on while skiing groomers with a bit of versatility too. The SN 100 is pretty good for groomers, but where it really excels is worn out, chopped up, variable snow. It kills it. Now, if you like a groomer experience that is very damp and stable, the Line may be your cup of tea.
