Are you familiar with ____ method?

Most likely yes. While I may not know their repertoire to the degree that I know the Suzuki books, I am familiar with most of the standard methods and what they have to offer. They all have merits, but in my opinion the Suzuki method is the most comprehensive, and better organized for development and reinforcement of musical ability. And, I feel the repertoire provides a superior foundation to the others. I do not use it simply because it is my background, it is a conscious, educated decision.
