I found it (googled)
http://store.nexternal.com/shared/St...unt2=613425850 The website doesn't say anything about a demo program, I don't recall if it did before, or the woman "Renee" just told me about it. I hope they still have it. Several months later, this past October or November my husband used the demo program for men's SI saddles too. Good luck! (If you buy a saddle, they send you a new one, the demo saddles are just for demos!)
