This always seems to be a "loaded" question. Everyone is different so what is comfortable to one is not to another. I had a Mustang on the Lowrider, was fairly comfortable but seemed to lack support on longer trips. My Fatboy has a Corbin. I love the Corbin. Some people say they're too hard. One thing to keep in mind when you're looking at seat, your butt goes on it not your hands. I say this as people will walk up to my bike and put their hand on the seat and push on it. This is often followed by, "THAT'S TOO HARD!!!!".
