I found the Turbomatic (with cut-out) to have similar firmness to the SSM Glamour Arrowhead, but it was just way too domed, so it wasn't as wide as listed. My sit bone ended up straddling the saddle. It was ouchie. Too bad, since I think if the back end of that saddle were flattened that it would be the best. saddle. ever. I do really like the Glamour Arrowhead, though, but sort of wish the cut-out were a bit bigger. It is a hair firmer than I'd like, too, but my sit bones are adapting. Something with firmness midway between the Jett and Ruby or Jett and Glamour would be perfect.
