You neglected to post some of the addendums that followed this message <vbg>. The shutter bounce vibration in the 6x7 is largely myth. Ask Bill about his standing nickel test. Furthermore, the 645 has a film curl problem due to the way it winds. In the 6x7 film curl is much less of a problem. And of course the negative is MUCH bigger! Paul The brotherhood
