My Fuji GF670 is just as quiet as a Leica. It is great for candid & street work (although I wish it was wider) In louder situations, it is sometimes hard to tell when the shutter fires. When I was recently at Niagara Falls w/ my Pentax 645N the shutter and motor drive were turning a few heads. I wish I could shoot my 4x5 more. If I go walking w/ the family, the 4x5 gets left at home because they don't want to wait for me to set up a shot. It is funny to come home after going out w/ the 4x5 and declaring to my wife that I only made one exposure.

Another great camera I have owned one of those and a Fuji 645-60mm. Have you seen a Leica M camera? They are tiny in comparison. I have never owned Pentax 645 or 67 but they look like beasts! Still the IQ is excellent many have used them for years. Glad you have that much confidence to narrow a session down to one exposure. I am not so confident. I will typically shoot several frames to cover any defects in the film, the load (have you put one in emulsion side down yet?), exposure, focus, etc and it doesn't hurt to have a spare. Rodney Lough shoots exactly 2 sheets of 8x10 at a scene and he is ultra meticulous so he gets good captures and doesn't waste money.
Shot off 6 frames on the Fotoman and wow does that system work well. Fast, small, light, and completely brainless. No batteries, no meter, the frame count is in a small window, focus with a DOF scale. You can get the film absolutely flat by tweaking the tension on the two knobs. Did some critical focus shots for starters. Then I will do some zone testing with a nice calibrated zone card.
