How much does she weigh, and how long is the Omni? Can you describe more what she doesn’t like about the Omni? Omni is a great ski-the union would be a step down, but if she’s sinking on the Omni the union may help at slower speeds. Lyric/senate is the radar version of Omni, so unless going larger to support her at slower speeds I don’t think it’s going to help.
