If the Specialized Toupe has less padding then I'd understand entirely. On long trips more padding is more uncomfortable. At least for me that has been my experience. And I've ridden several 100 mile rides with no chamois in my shorts.

The Power Comp saddle on my Tarmac that I got last year has some gel or padding of some sort in it that makes the first 20 or so miles very comfy. But when I go past 40 miles it's more annoying than the Selle Italia something or other I had on my Paramount. It was less padding and more comfortable for long rides.

But the Power Comp isn't a recommendation for you to try. It's still a road bike saddle and it sounds like you really want something for upright sitting.
