I pushed the AF of the D7000 one more step by adding a 2x TC to my 600 VR for BIF : finding the moving subject in the viewfinbder with a narrow field of view of a 1800mm focal length (DX format) was a challenge on its own, but the AF system of the D7k did help a lot to quickly acquire the focus on the bird.
The tracking system worked best with the combo AF-C & Dynamic 9 points (9d), the AF system was set to "Release Priority" and the Lock-On set to Normal.
