Tehered shooting is fantastic for studio setup. Not only can you see better what you are getting but I set it up so my clients can see too and they feed off of this doing far better than if they were not able to see. I had a groups of girls one time to shoot, but one at a time. My 26 inch monitor was setup so all could see it. All the girls who were waiting their turn were giving support to the one in front of the camera and they were all feeding off the images coming up on the monitor, making suggestions for poses, actions, etc. and really giving positive feedback on the ones that stood out to them. If you don't shoot tethered yet.... you should.
