Brooks. The Pro and B17 are different widths (about 10mm difference?).
Are you talking about the sit bone area or horn? And yeah, I agree since the width all-around of the Fly seems to work for me.
FLY is Length x Width -- 277mm x 140mm
B17 is Length x Width -- 280mm x 170mm
Couldn't find info about horn width or how either transforms from horn to sit bone area (correct terminology?)
B17 seems much wider than the Fly. Maybe that's a good thing?
