I really need your help. I know if I go to a LBS and they will tell me which one is best based on what they have on their shelf and probably they would not be knowledgeable about the entire lines. I already email Brooks people and I would also like to get your feedback too.
I am 5'8" with a thin build at 135 lbs. This will go on my 12 speeds steel road bike with a Nitto Dove/Oxford/North Road/ bar. I ride about 30-50 miles a week in the city and at most 10-20 miles continuous a day. I noticed that when I sit upright as opposed to sitting aggressive, my lower back pain after riding is drastically reduced. Oh, the streets of SF is not that smooth and there are some major hills to climb.
So with these conditions, which saddle do you recommend? I hear some good words about the Flyer and B67 but are they for me?
