I know nothing of Regal, so I can't compare. Other than a Brooks B17 knock-off (Record or Italia saddles), I ride the Selle San Marco Zoncolan. All saddles hit my seat bones in a similar manner. The C15 is a bit softer, but I get no numbness from using it.

But the sculpting is exquisite. As are the finishes. Far beyond any saddle I have ever seen. ideo did a great job.
