I had so many problems finding a saddle that I felt fit me correctly. I didn't do a demo program. I bought a saddle and used it till I couldn't anymore. Luckily I have very good luck with selling items on CL. I would usually break even or lose only a couple bucks so it was never a big deal. I landed on the fizik arione for about a year and thought it was perfect till it wasn't. Went to a fizik tri2 which was essentially the same shape just a little softer which I liked but was a bit to narrow for me. Now in a specialized romin evo pro with carbon rails and I'm loving it.
In total I am on my 13th saddle. Had some really bad experiences on some and some weren't horrible just not comfortable. The Cobb saddle was the worst for me BUT was partially my fault that I bought it 1 week before a century ride. I literally had traces of blood on my chamois! Taking a shower after that ride was BRUTAL.
