Hi Muirenn,

Thanks so much for your response.

Based on my Brooks, my sitbones are 115mm c-c. As I recall that is also what they measured using the Specialized sit bone measuring device, which, according to the shop put me between a 133 and 143. The dents in my Swallow are just inside the metal cantle. Of course if I'm sitting on the metal at all, it wouldn't show a dent...hopefully. : )

I do get some top-of-leg/buttock chafing on my Brooks. That starts after about 6 hours early in the season, and as my butt toughens up, it takes longer. It's worse with some shorts than others.

The Ruby was giving me boil-like saddle sores at the top inside of my leg, about where you might feel a groin pull, so maybe it was the cut-out.

Funny that the Selle Italia Turbomatic is in your list. When I was in my 20's, my favorite saddle was a Sella Italia. I think it was just Turbo then.
