Here's another thought. . . I much prefer the light, unweighted keys because for me it is much easier on the fingers to play 4 hours a night, five nights (or more) a week.
I noticed that when I had the G800, and even the X1, that my fingers would often be stiff and sore the next morning after a strenuous night. Maybe that's just another down side to getting old and brittle!
Personally, I can be more expressive with the lighter touch anyway, but that is most likely learned through many years of use.
I guess that's why we have choices.
