For you guys who shoot car racing and the like, does the rule of thirds still apply to action shots? I was looking over my photos from this weekend's autocross, and almost all of them are center-framed. But, to my eye, if I crop it more to a thirds shot, it just looks strange. Specifically I'm speaking of panning-type shots where I'm at or near fully broad side to the cars. I have a few going/coming shots that are off center that look great.
Plenty of examples here: http://www.zooomr.com/photos/bthed19/sets/28548/
Also, after cropping nearly every image, I definitely have zoom lense envy :-/
