As others will know, I am a big fan of the Omni [i have an Omni Syndicate] - I have posted about it several times on BallofSpray so you could search under Sivota or Omni. The slightly increased width gives greater stability without appearing to lose any performance. I was given one as a present and so did not try it before I bought. My skiing has improved enormously, and I enjoy skiing on it.
@MuskokaKy is right, you will hear a lot about the Senate, which obviously is a very good ski, but it is not the only one out there.
@savaiusini and @MarcusBrown know the ski well being part of HO, but they are also well respected. To be able to try before you buy seems to me to be a no-brainer. You have nothing to lose and may be excited about how you ski on it. It not, no real loss.
Whichever way you go, good luck. Once you are in the course it will be more addictive than you imagine - and you can freeski when you want to.
