In a perfect world, the saddle should disappear beneath you. You may not know what works, but your butt will. Go to a shop that lets you try many saddles. Your butt will show you the way. Even then, when you change saddles it will take several weeks for your body to adjust to it. Typically, I would advice against too much padding in a saddle, because the real padding should come from the shorts, but if you are doing without.... Finally, proper width is crucial and proper tilt is next crucial. If you really want to extend your comfort time, get a saddle that fits, get high quality bike shorts/bibs, and use chamois creme to reduce friction.
