You might be right on them all being the same, which would be weird on the tactility. I might be misremembering about the Realtorce.

The weighting does effect the tactility though pretty strongly. The heavier are more tactile, or at least feel that way, while the lighter ones are almost linear, almost exactly as he described, in the one I borrowed from my topre fanboy classmate about 10 years ago, so the memory is a bit fuzzy
