Play without a dampener, play with a smiley face dampener, then play with a worm dampener. Then come back and tell me whether you noticed a difference in how it plays.
People who say vibration dampeners don't change the way a racket plays aren't perceptive to one of the most obvious changes in racket playability. The bigger the dampener, the more dead the lower half of the stringbed. Night and day difference.
