I have to agree with Rod. 

I have not had the pleasure of riding with on a Day Long seat, but they are the favorite of the long distance riders who like to ride in events like the Iron Butt Rally.  Warning - for some bike models they can be butt ugly.

I also have not had the opportunity to ride on a Rick Mayer saddle, but I do own one of his brother Rocky/Bill Jr's saddles, which has been very comfortable for the last 42,000 miles.  It was their late father (Bill, Sr.) that designed the Russel Day Long Saddle.
