Would love to fly a Skycrane Helilog56... but back to the topic and using your words, a few years ago I was flying a Mi-8-MTV-1 with no vibration absorver mounted on the rotor head and on every single approach, no matter what power management or approach angle whe had the feeling our retina's would detached at any moment and I had to keep my mouth open to prevent my teeth from destroying while colliding with each other.
Then there where the other ones with the dampers mounted which felt much smoother.
My smoothest helicopter so far has been a well tracked and balanced AS350.
