In the end, you try new things and learn. Most riders here have a shelf/container of things they have tried and, for whatever reason, just didn't want to stick with. In mine I have an old "gelflow" Turbo saddle from years ago, moustache handlebars, weird foamy bar tape "better than cork", gel pad shorts, spring loaded fold-down aero bars, Performance tires, etc. If you really don't like your Ultras (and few things are as subject to personal taste/whim as cycling gear, use 'em for trainer tires or as food for the gread god Experience.
