I'm about the size of the original poster (6'2", 170 pounds). I have put thousands of miles on a B17 Champion Flyer Special on my commuter bike. The 170 mm width of the B17 is just enough to put my sit bones comfortably on the leather hammock region of the saddle. In contrast I bought a Craig's List bike this spring that came with the narrower Brooks Professional. Tried to ride it for months but I found I could never get comfortable. My sit bones measure about 123 mm apart, which sounds much narrower than the width of the Brooks Professional (160mm) or B17 narrow (150mm). However, while my sit bones sit entirely on leather on the B17 models (very comfortable), I found my ischial tuberosities were located over the substantial steel frame/rivet border sides/back of either the Brooks Professional (not comfortable). I replaced the Brooks Professional with a new B17 special, and was instantly happy again with the saddle. I think the B17 model has been in production so long because it is wide enough to fit most male riders, even those that are taller or wider than the average bicycle racer. The narrower racing models look great, but don't forget that the rivets and steel rail take up substantial width, and will never break in if your sit bones happen to rest above that region, instead of the leather surface between the frame/rivets.
