I think you got it all mixed up here, anything that comes at you is very difficultto track and I don't care if you're using Canon, 40D, 50D,1D Mark III or Nikon D3, D300, I shoot a long side with guys that use those cameras and hear their complains all the time. As good as auto focus performance of theses camera gets, the AF results are not consistent if the subject comes at you. My experience is that if you shoot moving subject, always use AI Servo and practice on the subject that you're interested, and I mean practice a lot because not all moving subjects move the same. Birds move differentlyfrom tennis players.
