Do pros use power pads and also whats the advantages and disvantages if there is any. Also what are they, describe how do you put them on and what do they look like and so on. Also why is it that all the pros I see seem to not use vibration dampener. I don't really think there is much of a difference in feel also that sound has got to be annoying. If you don't use a dampener what are your reasonings. Thank you.
