That's your entire problem right there. Your butt's not broken in. No saddle in the world is going to feel comfortable for you if you're only getting on your bike once every 2 months, and then riding 4 hours. If you ride your bike every day, say like for half an hour to an hour or so, it will toughen up the muscles around your sit bones so it won't feel like you're sitting on a brick when you do the occasional 4 hour ride.
