Buicky, yes, that's the word I was looking for!
Re. the shape, I intentionally skipped the step that makes the middle section of the saddle narrower. I did this partly out of laziness, and partly because I was curious how much it would matter. A lot of saddles that are popular today, such as the Selle Anatomica line, don't have a narrow center section; and no one complains. And I'm still not sure it matters, except aesthetically. But who cares if a saddle is ugly --ahem, i mean, buicky?
