Saddle comfort

Hail, mighty monocyclist’s,
I just got my first unicycle, a Nimbus II 20 (blue) with a Nimbus gel saddle. After setting it up, I rode it for about an hour and got some serious saddle soreness. The saddle was set nose up as far as it would go. I learned to ride on a friends unicycle which had a saddle made by Jorg… something. It was much more comfortable, but kind of thin in the foam, and I didn’t look to see how it was set up. I was wondering how the community has dealt with this issue.

To improve comfort:
Is it set up? Shift the saddle front to back.
Is it the saddle? Should I be looking for a different saddle.
Is it time? Break in my butt.
