Football games & 5D MK3 Settings

Hello,

I was wondering who all is shooting high school and college games with their 5D Mk III's this year and what auto focus settings your using to get most of your keepers? Also, anybody playing with auto ISO in tandem with Tv? I've noticed that the light is changing so fast constantly that I keep cranking the ISO higher and higher, but I'm still getting a fair amount of keepers. Just wondering what other people's experiences are?

Thanks in advance,
BK

Ai Servo with center focus point. TV mode with Auto Iso will work ok, by the mid 2nd quarter this time of year the light seems to be pretty consistent for the rest of the night so you dont have to be on auto iso, I tend to stay in manual and adjust settings as the game goes...
