I also owned the Undisputed in a couple different sizes, and while I found it better in pow than the Omni, I was not a huge fan of it either to be perfectly honest. I should've been more clear, it was a combination of taper and setback inserts on both boards that made switch riding more awkward, granted I'm not the best switch rider by any means.
