Definitely try to speed up a bit more as you dive. Flank might be a bit to much noise drawing attention. Though you might get away with it anyway, worth a shot. But surely 2/3rds or full doesn't get you noticed right away. Either way, it's more safe to get down quickly ASAP, than to stay quiet and not move. If they get you on their active sonar and you are still shallow, well ... sitting duck syndrome.
