I'm a Brooks refugee. Rode my B17-Ti for many years (96-06), believing it was the end-all/be-all of comfort, until I decided to see what the ergonomics revolution had produced.
I went to a Specialized dealership (with a seat exchange program) and just started trying their whole line. Tried the Toupe, Avatar, Alias, Romin, and a few others in the various widths. Found some that were PERFECT, but then tried others that were even more perfect. After two months of extensive testing (and smirking from the LBS employees) I finally settled on the Avatar 155. It has a junk-chute down the middle to avoid pressing on your perineum, and two perfectly-positioned gel pads right where your sitbones are. Perfectamundo.
The old Brooks is still on my Masi wall-hanger, and I still ride it now and then. But it's not nearly as comfortable as the modern, plastic-fantastic seats available nowadays, IMO.
(No offense, Brooks fans. We all have different butts.)
