Just don't forget that your faster film can stop the props in your pictures.
Yes, but... Use the faster film speed allow you a smaller aperature (high number, but smaller opening) than what you would get with a "slower" film in the same light. The smaller the aperature, the bigger the depth of field. Larger depth of fields allow you to compensate better in case you are slightly out of focus. This way when you are getting shots of the fast movers (or just movers in general) and don't really have time to check the focus, you have a better chance of getting a good shot.
In case you don't know... the depth of field is the range between the points closest to you and furtherest from you where the subject you are shooting will appear in focus. So the bigger you make this range, the better your chances of getting a good picture.
Always (when possible) set-up your shot by doing a focus / range check on something close to where your subject will be, before your subject is in view. This will help ensure that your subject will be in that depth of field / range when you take the shot.
A bonus is that as you make the aperature smaller, your shutter speed will be slower, allowing you to blurr those props. You tend to get prop arcs around 1/250th of a second, and good prop disks at 1/125th of a second, but each case is really different.
I too would be interested in what the photographer has control over when shooting with digital.
