Hi! I have SJP & stepbast as well as rhytmic step. I started out with the Reebok adjustable step because it was less expensive but I ended up buying the club size step a few months ago. It is worth it with Cathe's choreography. Some moves that come to mind are the flying angels, the l-step and over the top lenghtwise. I don't have to watch my feet so much so I don't accidentally fall off and I can let myself go with the flow. I'm glad I have the larger one but I guess the smaller one will do if that's all you have.
