Also, for the record, I have only ever had one saddle sore and it was on my Selle Italia Flite after just 8 miles in halfway decent bibs. I switched to a Brooks saddle AND use the Butt Paste everytime and don't have any sores. It's either the saddle, the paste, my position, or the skin of my butt getting used to a saddle that have cured the problem. My thinking is this: If I go out without the paste and get a sore, then I'm uncomfortable for my next ride, which would bother the heck out of me, so I just put it on as 1/3 oz. of prevention.
