Just confirming what Knotted said. My sitbones are 155-160ish and I'm going for the B17S, just because it's closer to 170 and should be more accomodating to my wider base. ;) What was hard for me was learning that though I have a skinny butt, my bone measurements could be a little wider than expected- AND that I was sitting on my seat ALL WRONG. I had all my pressure on that little bridge inside one's thighs and very little on my actual sitbones. No wonder I was getting chafing issues, etc...
So... I hear ya. =) I'm sure the more seasoned Brooks pros will be able to confirm/deny my assumptions.
Also... I'm getting my 1st brooks this weekend!!! YEE!
