Her first tape was a learning process for her, the first one she has ever done. If you can overlook some cueing issues, etc, it is well worth having, imo.
I think all of her tapes are great, she is definitely the "heir apparent" to Christi Taylor, great new moves, complex yet fun and intense.
I would get them all and start with her newest, SUS. Once you get her style you will be just fine!
