Have you already got a V8? The dorff weighs about 5X what my Chamonix weighs. I can't see giving up my 4x5 cameras and committing to lug around the V8 to shoot 4x5. I base my format use mainly on the type of lenses I want to use. Lots of interesting lenses won't fit on anything smaller than a 6x6 board. To me, there's a huge difference in carrying around my Cham and the V8. I might feel different if I owned a really light 8x10 camera.
