Just Locs

I am in Charlotte, NC and I have decided to start a natural hair business. I have plenty of prior experience and God has already blessed me with wonderful clients. I was considering taking the Sisterlocks training classes and I am interested in knowing whether it is worth it. I have developed my own technique that is working, but some people are set on having "the real Sisterlocks". I met a wonderful sister today that wants to experiment with my technique on her Sisterlocks and I am so excited, because this is the one service that I don't offer right now. Please give me some input on this.
