I went through 4 other saddles before breaking down and trying the "probably overrated" Brooks saddle. I then found out it wasn't overrated and was the best saddle I had owned. I have the Brooks Flyer (the 2 spring model) and it's great for me. It's slick so as others said, less friction. Coupled with a firm surface that's the right width for my sit bones, it proved to be the most comfortable saddle I had ever tried. I've put roughly 750 miles on it since I got it. I can see very slight indentations from the sit bones on the saddle now though. I didn't want to oversaturate the saddle with proofide to make it too pliable.
I tell everyone that the hardest part about cycling is finding the right saddle for them. There is no one perfect saddle in the world. Everyone needs to find what works for them.
