What Bionic Turtle Package Do You Recommend?

Hi, I am interested in taking the FRM Part 1 exam in May 2017. I understand that it is too early to sign up and buy study material but I would like to research study providers beforehand. From reading this forum it seems like using the GARP study materials and Bionic Turtle is a good combination. I’m open to suggestions on other study material if there are other providers that are recommended. But for those that use Bionic Turtle what package do you recommend: Basic, Advanced, or Professional?
