This just goes around and around. My late brother once sold Rollei and Linhof cameras. He'd demonstrate how the Rollei SL66 shutter was so smooth by setting a dime on edge atop it on a table, then tripping the shutter, and the dime didn't even tip. If you tried that with a P67 the dime would land four blocks away. But, even though he owned two full SL66 kits of his own, he preferred to borrow my Pentax 6x7, and got even crisper shots with it!
So you need to look at the overall scenario. At speeds higher than approx 1/60th, the shutter has already done its thing before the mirror hits, so there is no practical effect to that "shake" other than a bit of noise. At lower shutter speeds, you can simply use the mirror lockup feature. But I've got a couple of beautiful coffee table books based on P67 shots before the lockup model even existed.
Yes, P67 teles have improved over the years, with long focal lengths going from good in Takumar days to outright superb in the later EDIF series; and the mirror lockup feature is a real bonus too. But all this shake worry is unwarranted. All kinds of cameras have trouble if a substandard tripod or head is involved when it comes to long lens usage, even 35mm SLR's.
In terms of effectiveness of dampening, set up your 6X7 on various types of tripod materials of similar alleged weight rating. Place a fingernail against one of the legs when you trip the shutter. You'll feel it with many metal tripods, but not on a wooden tripod leg. The cellular structure of wood is actually an extremely sophisticated kind of natural engineering.
I once sold surveying tripods. The serious ones were always wooden, although sometimes fiberglass clad for weather resistance. And it's actually fairly easy to convert one of those for MF tele usage, or large view camera usage (just avoid PRC import knockoffs). They don't pack up as compact as typical camera tripods, however.
