Since Shakespeare is produced in so many different, creative ways, you might pick Rosie. The moral is- don't second guess the director, just be yourself and make your own decisions from your own life experiences. In addition to the sound of your voice, the director is looking for the vocal quality. This reflects on your ability to make decisions regarding the characters you portray. If the casting director thinks you are completely wrong, then chances are you will make the same wrong decisions if cast in the show.
Brevity is the key to auditions.
Keep in mind that the casting director has looked through tons of resumes and headshots, and been auditioning for days. The last thing he or she wants is the auditionee with a ten-minute monologue. This is especially true if it only takes ten seconds to make the decision. Many times if you exceed one minute, you will be stopped. Being stopped in the middle of a monologue can be quite embarrassing and disheartening to an actor.
