Luffy, Crocodile and Enel are the ones who have great mastery over their DFs. For me a master DF user should use another way of his/her DF except the fruits' primary usage. In their case Luffy's gears, Crocodile's ability to suck moisture to turn things to dust and Enel's ability to make his heart beat with electric shock and hearing electrical sound waves.
