It was more like a thread within a thread where the question came up, was discussed some and then lost again in the main topic. No real information was gleaned, at least not as good as being in the wind tunnel with John Cobb on a Titanflex and comparing a disc rear with an H3 rear...sorry for the difficulty in finding that thread...I don't think it exists in the form your search would pull up.
