I remain in awe of ye who actually understand ski design and construction.
I don't bother to worry about the details because I can make the effort to get to free demo days in more than one region. Know enough about brands and the basics to pick skis for a run or two to decide whether they are fun for me or not. I actually learn more from skis that I don't like than ones that I expect to like, so don't really care what I demo. Just need to be somewhat in the right ballpark for length, but the range can be plus/minus 10cm from the optimum length.
First free demo day was about a dozen years ago when I was still an intermediate (small mountain in NC). Took out a pair of 4FRNT powder skis for kicks. After that, I understood what "turn radius" meant.
