I saw, and sat in the Ergovation yesterday at T.C.I. It was a prototype model, and most of the attachments are not even available yet. It is a nice saddle, and is very versatile. The designers wife is a physical therapist, and was the main influence in it's design. It is comfortable, and will help climbers with sore backs. You can basically put any type of seat and bridge on it. But it won't be for everyone, especially sine the saddle will be around $589, then each additional add on will be extra. It seems that ever since the treemotion was released, it's been a race to claim who's saddle is the best. Honestly, all of the arguing, and whining is ridiculous! We are supposed to be a community of arborists! Everyone has their preferences on what is the "best" saddle, were all different, and that is what makes this Industry so Great!
