Another thing I do, is if I know I want to shoot the action picture in a certain aperature. I will goto Aperature Priority (AV) and set it where I want it, lets say 2.8. Then I will do a half click and see what the suggested shutter speed is. If it is too slow, then I can adjust the ISO to another setting and recheck till I get the shutter speed I want. Then I set all my settings in full manual and shoot away!
