Good post and glad to hear about the problem being gone. I used to experience pain in my left knee and now I can not ride with a fixed cleat - must use pedal/cleat combo that allows float. Recently purchased a new bike and bought the Look CX-6 pedals and I too have wider than average hips so the Q-factor adjustment is very nice. I started out in the closest position to mimic my old pedals and then made a couple adjustment over a couple weeks until I got to a wider position that I felt was more comfortable. Now I feel as though I can push the pedals harder and my feet are more comfortable over long rides also. I am always amazed at how much minute adjustments can make a difference.

Glad to hear of your good results with the CX-7's. Almost opted for the CX-7 but at $200 more than the CX-6's I decided to take a chance. I hope that one day the new Keo's have a Q-factor adjustment because they look like a great pedal with their lower profile.
