Great tutorial, thanks.
I've been regularly covering FC United of Manchester since June 2010 (Pre season friendlies seemed a good time to try it), and have even bumped into Kipax a couple of times now.
I tend to set my camera up in advance with slightly different settings for Tv, Av and Manual.
This way, depending on the light, I can flick between settings rather than being fully manual at all times. I also find it helps with the crowd shots.
I tend to prefer using Shutter priority as I too suffer from darker images on Manual.
