I have several pairs of the Sugoi shorts and the Performance Century shorts - both gel and non-gel and love all of them. I've ridden several centuries in the Perfomance Gel shorts and I've never had a problem with saddle sores and I don't use Chamois Butter. But like Nanci said - it's truly a personal thing and you might have to try several pairs before you find whats right for you.
Let us know what you get tho - we're ALways interested in hearing what other women are wearing. (or at least I am - sorry about speaking for everyone else! LOL)
