Nice reposte Mark, your library of videos is uber cool

As an engineer going for the ultimate goal always incurs penalties of some form or other. My worry is that we are totally into trying to get the ultimate platform stiffness but incurring penalties such as weight and cost for what may or maybe not be small incremental gains.

But will we push through the point where it suddenly gives problems to us as humans. I remember flying a pretty state of the art glider in the 90's with carbon wings, it was so stiff that every bit of air turbulence was transmitted into the **** and litterally was jaw chattering at times. Flying the less state of art glider with glass and carbon was like flying a comfy arm chair where you could feel every thermal and puff of uplift. Now myself and others were pretty agreed that over a day the softer platform would be a much more forgiving and hence better aircraft to fly.
