Hi there. I am looking for a Brooks for myself, and would like some help. All the photos show a side view of the saddles, making it hard to tell the difference between each model.
I am leaning in favour of the B67-S, but am also considering the Countess. Each is sprung, and I can't discern any differences.
I ride in a fairly upright stance, with my saddle level-ish with my bars, and use trekking bars.
According to my memory foam pillow (thanks for the tip, jcm), my ischials are 5.5 inches (140 mm) apart, centre to center.
