Sorry. I hadn't noticed that you edited out that paragraph at the time I replied. If I now delete my response to your missing material, it will make following the thread even more difficult for people, so my vote is to let the old stuff stay as is, and just move on to your other questions.

There are two things going on simultaneously. One is the amount that the ski itself is vibrating, and the second is the fraction of those vibrations that gets transmitted through the plate/binding system to your boot. Imagine you had a totally un-damped ski that was clanking around like crazy on hard snow, but was connected to your boot by a very soft, long-throw set of springs under the plate. You would feel almost none of the wild vibrations/chatter of the ski, yet they could easily degrade the ski's performance. At the other end of the spectrum, you could have an ultra-damp ski with your boot practically welded to it, and once again you would feel only very modest levels of vibration/chatter (but for a very different reason). So, what you feel in your feet is only indirectly related to what the skis are doing. When people refer to a "damp ski", they are talking about the ski itself, not what is transmitted to your feet. The former is controlled by the design of the ski, the latter is controlled by the design of the plate/binding system.
> ...When said vibrations can be felt, are they significantly affecting the ski's performance? ...
Sometimes they do, sometimes they don't. It all depends on the amount transmitted up through the plate/binding system, the fequency, where along its length the ski is vibrating (aka, "the mode"), etc.
> ...Do others agree with concept that there is a tradeoff between dampness and "pop" (energy, liveliness, etc.?) Could a skier feel dampness as "stability"? ...
Yes and Yes. With respect to which specific models are damp, I hate to admit it, but I've been too busy teaching to demo any new models yet, so unfortunately, I can't respond knowledgably.
