That is the type of photo where live view would be the least helpful. When you are using a tripod you have time to experiments with camera location and framing. You will allways get a better view with the optical view finder, no matter how good the LCD is the real thing is better.
Live view might be usful for the times when it is hard to get your eye to the camera, maybe if you are holding the camera over your head to get a photo over a crowd.
I beg to differ. When I'm doing tripod work, I use Live View a lot. I might do my initial framing with the viewfinder, but then I switch over to Live View for the rest of it, especially for manual focusing. There is just no substitute on a cropped sensor for being able to zoom in 10X to see just how well you are focused, especially in low light situations. Also, if the tripod is not set at standing height, which it rarely is for me, I'm very happy not to have to stoop over or squat down to look through the viewfinder.
