I've been shooting my 6x7 for over 25 years. I've put it on a lot of different tripods. The thing is, you can get by with a compact tripod if you do not raise the camera to eye-level. And I believe it's the curtain inertia that is the driving force in camera shake more so than the mirror. You can also reduce this when using a smaller tripod by adding dampening. That is, a sandbag-type weight on top of the camera. You can use your hand to gently push down if you have fast enough shutter speed.
And when we talk "big tripods" for the 6x7 we really need to also talk about which lens and shutter speed in the same breath. I have handhold shots with the 55mm that are pretty much as sharp as any tripod shot I've done. So these wide lenses can do even better on a modest-size tripod.
So lenses like the M* 300/400mm ED IF can be the most difficult and can benefit more if you use two tripods instead of one. Mount one on the lens mount and one supporting the cantilevered camera body (can also use a mono pod for that).
If you want to test your tripod and camera for shutter vibration, set it up and take a shot. Next slap on a 9 or 10 stop ND filter and get the shutter speed down to say 30+ seconds and take a shot. Any shutter vibration will not be recorded due to its short duration compared to the overall exposure.
