RS is my favorite Cathe and I would love RS2, but I'm very happy about the circuit, cardio & weights, and bootcamp tapes. Sure The Firm does tapes like those too, but I like Cathe better! I have lots of Firms I like, but there is something a little off in each of them. Plus, Cathe's will be on DVD. I'm also lucky that I've never done any of the Cardio Classics and they will be all new to me when that DVD ships.
