It all depends.... I shoot manual if I'm taking a series for a pano. I shoot aperture priority most of the time - because I want to control DOF. I shoot shutter priority if I am walking around in the woods with a 50-500 OS - I keep the shutter speed at 400, leave OS on, and set auto ISO - it lets OS work wonders for me while hand-holding at 500mm. It all depends, but these cameras are darn smart and the D7000 is the smartest ever. The matrix metering works wonders, so do the scene modes - shoot aperture or shutter priority and add +EV for snow and beaches or shoot scene mode for snow and beaches and watch the miracle. There is no one right answer other than knowing the capabilities of the camera and taking charge when you know the camera may get confused or you know what the programmed answer is and you don't want that answer - that happens less and less as these cameras get smarter and smarter. IMO.
