You did give me some more ideas and I will see what I can price the 70-200 F4L (even though it has less zoom it appears to have more focal length)?
With autocross you wouldn't need to shoot less than f/4 anyways, most likely being f/5.6+ depending on how bright it is and 200mm is plenty of length for cone dodging. :my2pixels:
