Rode Brooks Professional and B17 for years on my touring bike. Just this year I changed to the Sella Italia Turbo saddle as I have had one on my daily rider since 1986. Not sure what changed, but anything over 140mm kills me now. Not sure what changed. I can do 60 miles without much issue on it.
Every butt is different. Perhaps that is why dogs and guys spend so much time looking at them checking out the differences.
