The Brooks Cambiums come in widths wider than the specialised saddles, with a similar shape to the B17 but they have a relatively wide nose, and a really nice, gradual taper. I don't ride with a ton of drop but can hold a really aggressive position on one no problem. The higher the number, (cambium c13, c15, c17,c19) the wider the saddle gets. They have a carved version as well but I haven't found that to be necessary.
They do weigh a ton though, 450ish grams.
