If you don't think you'll use the rangefinder, then I don't think you're gaining much over the Gandolfi.

The rangefinder is still useful even when using a tripod. If you're shooting something that moves, like portrait subjects, you can work much more dynamically if you can leave a loaded holder in the back with the darkslide pulled and can focus at the same time. I do 8x10" and 11x14" portraits without a rangefinder, of course, and the need to focus, ask the subject to hold still, insert filmholder, remove darkslide, and click the shutter, means having to work with more static poses in general.

For landscapes and architecturals, the rangefinder can also be useful to confirm focus in low light or with wide lenses where it can be hard to see the corners.
