AI Servo is indeed a usefull AI tracking setting for moving subject but it don't cover the lack of AF tracking speed and accuracy of the body & lens infact by this method u might get a lot more out of focus picture compare to your one shot focus lock if u're not familiar with it
Oh yah...thats what I have experienced before and thats why I chose One-Shot for all. Maybe it is the cam....so am I right to conclude that the focusing are better for xxD onwards? I did try the xxD and xD, I feel that they are faster and even the 5D MKII which some people claimed that it is slow but I still find it faster than my 400D....maybe my expectation too low....hahaha
If 60D's focusing is a big jump from my 400D....I think will consider getting it....and probably pair it with a better lens. I am still having doubts with kit lens
