Your measurements and my measurements sound very similar. If you are interested in a Brooks, I would try a B67 or B68 first. I can't tell you what a huge relief it was to get a seat wide enough to completely support both sitbones! Even fresh out of the box, that B67 was the most comfortable thing I'd ever ridden on.

Now that it is breaking in to my unique tushie, it's even more comfortable.

Yeah, they are slippery and hard for the first 100 miles or so. Yeah, they make some noise (which can be minimized), but oh it is soooo worth it!

And it is just as comfy on my road bike as on my hybrid.

Wallingford has a 6 month return policy, so you get the chance to really try out (and break in) the Brooks saddles. www.wallbike.com
