What AF - Case are you using for what sport?

Using the 5D Mark III. Let use know what AF- Case AI Servo you find suitable for a particular sport. we need real life use here.
My first attempt at baseball was to use Case 2 and single point expansion. It worked most of the time but there were some that were out of focus when the AF didn't lock before I shot.

I am shooting Roller Derby with case 4, single point.

I used Case 4 for U12 soccer with single point focus. Still need a few tweeks though.

Rollerdery with 4 point expansion. Tracking sensitivity 1 click above bottom, Accl=middle, point switching=middle.
