My wife rode padded saddles on our tandems, mostly gel. After a certain amount of time riding, she would have to shift or get off the saddle for a moment of relief. That could be as often as a few minutes near the end of a ride of say 25 miles. I got her the B17S carved saddle to try. She was skeptical, but tried it. She found it so comfortable even as a new saddle, she no longer needs the relief breaks. She has 3 of them on our tandems and her single. I also use the B17 carved and the B17 Special on several bikes, highly recommended.
