People I know really like the Road Zep. Most bought it for passenger comfort as well as thier own. Keep a eye out on Ebay as they come up for auction from time to time.
Good Luck,

I've been using a Corbin Rumble seat (Back part flips up for passenger). Extremely comfortable for me (6'1" 230) on long rides- only good for short rides for passenger. I now have an '08 Roadglide,so the seat does not fit as they changed how they mount on the '08's.Now I have a $600 seat sitting in the garage!
