Just sprung for a new Jamis Coda Comp.

The stock saddle is okay but I am lusting after a Brooks (and trekking bars, but that's another thread). I'm curious...how many of you ride on sprung saddles? If you do, does it make much of a difference in your comfort level?
I chose the Jamis in part because of its steel frame; I'm pleased that it provides a much smoother ride than my aluminum road bike. I ride mostly on flat paved roads.
Suggestions and reccommendations welcome!
