You have two issues here, one is the saddle and the other is the bib or short you are using.
No idea what shorts are u using so is hard to know. Many times is not the saddle but the shorts. Some shorts sucks for the 1st ten rides and then start doing their job.
As for the padding, more padding doesn't mean is comfortable, if you want to try just get a short saddle with like 7 inches tall padding and springs and ride for 4 hours, I guarantee you that after 30 mins you will be asking yourself why you did what I said.
What shorts are u using to start with?? your nuts get numb??? only your bones hurts like hell???
