Music Man: which female part has the most speaking lines?

I am auditioning for a role in my schools winter musical and this year it is "The Music Man." I am really excited because it's such a great production. My goal is to get a speaking/singing role this year and I've narrowed it down to four that are listed below.

Amaryllis

Mrs. Paroo

Ethel Toffelmier

Eulalie Mackecknie Shinn

I'm a stronger actress than I am a singer, but I don't have a terrible voice either. One of the requirements for Mrs. Paroo is to be able to do a decent Irish brogue which I've never really tried but I'm expecting would be fairly hard, so unless you think that the dialect would be easy enough, we might want to cross Mrs. Paroo off the list.

Okay, so basically, of the listed above characters, who has the biggest part in the Music Man?

Thanks in advance!
