I could be wrong but the I think the primary difference between the Syndicate and Carbon omni is the core material. Syndicate has a more high performance oriented core where as the carbon has a more forgiving core. I'm just learning to ski the course and have been on the carbon omni for the past few months. The carbon omni is a great ski, very stable/forgiving but has allowed my to progress and work on form while also completing full passes. I am skiing better than ever on the omni and am actually progressing. I don't think you can go wrong with either, if you are just free skiing, the carbon omni is a great way to go.
