I've been having trouble fine-tuning Brooks and SA saddles on my bikes for comfortable riding at my 14-15 mph speeds over 50 miles, with drop bars. I'm finding decent comfort up to about 35 miles, but after that I just don't want to sit still. Often I have abrasion and, well, blood. I want to venture into Specialized saddles, of which I have a few lurking in the Saddle Box.
Have any of you rando and long distance riders found some Specialized that work better than others? What about other plastic saddle brands?
