I have shot several more weddings since I originally started the post and I still have the problem but have found ways to "live" with it. First, I shoot with the 70-200 f/2.8L IS II, the 50mm 1.2L and the 24mm 1.4L and both the 50mm and 24mm seem benefit (or at least are not negatively affected) from the AF assist. The 50mm just plain sucks in low light though so there isn't much helping it. However, the 70-200 has serious problems with the AF assist beam so I just turn it off when I use it and I almost forget there is a problem. I simply added the AF-assist enable/disable to MY MENU so I can access it quickly when I need to. The flash still works fine I just doesn't use the AF-assist. Just as long as I focus on an area that has some contrast I am fine even if it is really dark. I usually focus on a white shirt collar or another area that has contrast. At 2.8 if you focus on the shirt color the face almost always falls into focus as well. I have also adjusted the setting towards release priority instead of focus priority and I find that really helps me get a shot quickly. It seems that the camera does focus quickly but sometimes it just hesitates a little before it confirms with the red light. Overall I am very happy with the camera I am just so frustrated that the AF assist beam makes focusing a lot worse with some lenses. I am also frustrated that CPS says they have never heard of the problem which means they are lying to me.
