I have found this setup to be great when shooting moving subjects as they can move into a different exposure scenario pretty quickly. By leaving the focus on AI servo, a quick touch of the * button will give you instant focus like the 'one shot' setting and holding it down will make it track like the normal AI servo. This is very useful as well when using lenses that have full time manual adjustment. If the AF starts going wonky because it doesn't like what you are focusing on, you can do a manual adjustment and click the shot without having to switch the lens from auto to manual and back. It took some time to get used to but I don't think that I could ever go back now.
Anyway, sorry if you are already aware of this but I thought it might help you out. Don't forget to show us some shots.
