This is like the story of the guy who had a big, lush beard and was asked if he slept with it over or under the sheets. He got so crazy he went to the barbers to be shaved. Just do not know if there is a correct way to "wham" or pull off a note. Everybody has different fingers, hands, and fretboards. Just do whatever works for you and fits into your style of play. And if you like the sound you get, great!
