It seems like there a lot of talk about ski shape (Vapor versus Senate, Syndicate Pro versus Syndicate Omni, etc.) but is the build material more important that the extra 1/8 of width in some of these skis? How does the build material effect stability? Bottom line...is there more difference between a Syndicate Pro versus an Omni or more difference between a Syndicate Omni versus a carbon Omni or basic Omni? Any insight would be appreciated. Especially from people who have skied the same year/different build. Thanks!
