I used to have a B-17 on my road bike but switched it out for a Swallow. The B-17 is now atop a more upright city bicycle. I like both saddles a lot and ride them both with all sorts of clothing. I think that the narrower and smaller Swallow feels a bit better with the drop bars and also looks a little neater on the road bike. The B-17 works great on the town bicycle.
Like others have said though - you'll either love the brooks or you'll hate it...
