Yup...the Cobb article. If you had an issue with your pelvis and saddle rotation helps you ride without discomfort, by all means keep riding that way.
Good Luck...saddle comfort is hit and miss for most of us and go with what works.
PS: I have heard of others that rotate their saddle as personal preference but I have never seen it formally endorsed like Cobb does on his website which I referenced in another thread. Cobb is a thoughtful guy who has created his own saddle line and done probably thousands of fits and knows his stuff so I would say his suggestion has merit.
