For types of racing where you actually have to take your hands off the steering wheel in order to make the turns, what is the preferred steer wheel technique?  Most street driving classes teach hand over hand, yet many racing schools teach shuffle.  Is one preferred over the other or are both used depending on the type of racing/driving one is doing?
I've Googled and seen a number of sites, but any links with explanations you think are very good and shouldn't be missed would be appreciated.
Thanks!

 Not exactly sure how to describe it, I hold the wheel at 3 and 9 and use hand over hand if needed. The DFP is small and too strong for its size in most cases.
