For me, definitely the more I ride, the less the soreness holds over.
I just got a Jett a couple months ago. At first, I was pretty sore in the sitbones, but very happy with the forward bits! My sitbones are getting better and better with the saddle...the other day I did 80 miles on it, and I am fine. I REALLY like it for climbing, which is what I am doing more and more of, so it suits me.
Depending on the type of riding you do and what you need out of a saddle, you might have good luck with a Specialized mountain bike saddle for women. The one I had before the Jett was only about $35, and had the exact same width and cut out location. But, it was softer, and the "trough" for the girly bits was just not as pronounced. That saddle served me well for quite awhile...I just wanted a little firmer saddle...for me, I wanted the firmer perch on the back, and wanted the better trough for the female bits. But, I rode a couple centuries on that saddle, so it was OK, you know? Never had real numbness issue and never a saddle sore.
I can't recall the name of it right now, but I still see it hanging in the Specialized stores...it is sort of black vinyl looking, with some periwinkle star-like designs on it. Might work for you.
