Toupe is similar to Arione and if you didn't like that, I'd skip the Toupe too.

I was just saddle shopping yesterday and the super helpful LBS guy described the Romin & Fizik Aliante as "sit in the back and don't move around" saddles. They have something that almost looks like a backstop on the back, so they don't appear flat, but that might be better for how you've described your riding style.
