Ok... so I have a new question...
My Brooks is totally comfortable on my sitbones now... but when I accidentally shift down too low and end up spinning or brake too hard or something, I end up really smacking my soft tissue on the hard nose of the saddle, and 2-3 minutes of hugging the top tube with my knees while uttering unpleasant words is starting to wear on my riding partner.

Any suggestions? I have the nose tipped down just a little, and I'm wondering if I need to tip it back up after reading Triskeliongirl's post...
