if you are doing real road races, "comfy seats" for ;ong durations mean saddle sores. it's some sick and twisted thing in road cycling, but the aero seats are amazing past 20 miles... i have a selle itala ti-gel... fantastic...
but if you are not really hitting the roadie sport, then the terry butterfly is what i have on my "clunker" (bianchi eros... what a pile of crap??? hehehehhe only hard-core road would call a $1500 bike clunker)
i;ve also been on the f'zik for women saddle and that is super awesome. the flexing center works well and the smooth single piece construct means no chafing anywhere... but i ride tight and find the nose a little wide for me me crazy speed freak tho...
test them all out. most shopboys are super nice about letting you mount a saddle, ride around a bit
