I am willing to trade my JUST CLA'd Hasselblad 500C body with WLF, 12back and 24back, plus extra crank knob for a perfectly functioning Fuji GW670II or III.
The Fuji GW series are awesome. But of course do not have interchangeable lenses. I've had my GW690III for years. AMAZING sharpness and character. They are a bit bigger than the Mamiyas and unfortunately a little louder (TH-wunk) but it's not as loud as you think it is being right up with the camera to your nose...that all said you might consider a 690 as the size from the 670 is the same and you could always crop the 6x9 down to 6x7 and have both options. Less shots per roll is the main drawback...
