I have not noticed any of this wobbling with my B-72 so far. But then I also weigh in at about 110 pounds, perhaps that makes the difference.
That said, while the B-72 has provided what I was looking for by evening out the really vibration heavy parts of my ride (there are a couple of sections on the MUP nearby that go over wooden bridges for instance), it doesn't give nearly the amount of suspension I expect a B-67/66 would.
