I started out in ignorance, I assumed all saddles were uncomfortable and for a couple of decades just put up with whatever came on the bike. Then I started riding in groups, so wasn't short of advice, tried a Rolls and didn't like it, then a B17 which was fine until stretched and then a C17 which is pretty much like an unstretched B17 with a little more give.
Not sure there's much I can help with, try and work out how it isn't working, position can be as important as saddle, both position on the bike and on the saddle itself. I sometimes get a bit uncomfortable at the end of a long ride, it isn't the saddle, it's because I'm probably sat on it heavier when knackered, with less weight on my legs. There's some things that might help, suspension seatposts and padded shorts, but IMO they're fine tuning, they can't make the wrong saddle comfortable.
