Busy action,al servo V's AF one shot?

Hi again!
Just have a bit of a dilema that some people might be so kind as to help me with. When the frame gets busy with several players in soccer,it seems AF one shot is a little better for me, Al Servo gets distracted with movement from someone that might cross its path when locked on.

In saying this the AF one shot can be a little out of focus because of the delay in shutter as the action moves left or right etc! All shots I ever do are with centre focus point only. I realize that this is slightly a "catch 22" situation but I was just looking for some preferences from people. A seniors match I shot yesterday which I changed to and from One shot and servo to see the results favoured servo a little, But mind you I got some real sharp shots also from one shot. What is your most successful setting in a busy frame?
Thanks!

I have mine set to servo always for action and on advice from these very forums its set to slow so anything passing by quickly wont take the focus away so easy

Yeah I have my tracking sensitivity to "moderately slow"

its the same setting SI shooters use as well

Thanks guys.
Shot with servo and was careful focusing and now my keeper rate has just jumped up a good deal.
Thanks again.
