I agree with what someone else said on here that you will probably have to wait to see what "way" her hair grows. Puppy hair is always fluffy! By the way your little Amy is a doll! My Morkie has silky hair, so he takes after the yorkie in him. My mother has an all black morkie with hair traits as an maltese. Its funny to see them next to each other, you would never guess their the same type of dog!
I think you will be okay either way, expect their first cut to be "off" and it will be more on point next time!
I will have to find some pictures of Cruz's horrible 1st cut!
