I bike daily, ride trails and rocky slopes, as well as through woods. I've competed--although I don't any longer--and taken plenty of long road trips. If that's your description of a "casual rider", so be it.

It's interesting that those critiquing these saddles are generally those who've never used them, or have tried them for a short ride. As with any setup, it takes some time to get used to it. Once you become accustomed to it, though, it's so very much more comfortable than a traditional saddle, and there's no decrease in your ability to brake or flick the bike around obstacles.
