No one's mentioned the additional physical exertion that doubles require. It can be hard. When I first needed to use doubles my Diving Safety Officer would not let me go operational with them until I completed the circuit swim exercise in the same time that was required of divers wearing a single. It took me three tries with doubles even though I held the program record with a single.
