I've settled on Charge Spoon Ti saddles. Common in the UK; you can get them in the USA but you have to order. They are wide, light, full leather and very comfy on a road bike. Wore out the first one at about 10,000 miles.

I also like the arione CX. My uncle (same size as me -- 6'3, 210) swears by them. Charge spoon on my Ira Ryan in photo below.
