with 7D, I really don't know how people can use higher than 1/250 as some mentioned that motion need more than 1/250 !!! I wish I can but ISO just keep me from a low noise photo!
Outside the rink, indoor , for the presentation podium, with 24-70mm 2.8, always use 1/250 and up shuttle priority with high speed sync 580 ex flash. ISO can tuned down to 200 or 400. I am a hand shaker and use high shuttle speed to capture a non motion moment compensating the shaking.
