TBH panning isn't a great strain on the AF system. I tend to use single point AF in AF-C
IME 3D's not necessary for motorsport and find single point better. Obviously YMMV. I've never hit the buffer shooting motorsport, imo there's no need to machine gun as it's not as though you're trying to get the perfect expression or something that you would shooting people playing sports. In fact, I started shooting in continuous low as I just ended up with a lot of practically the same shot. Again YMMV.[/url]
