I swapped my RS backorder for the S&H series, then decided that I didn't have enough cardio and pre-ordered the new Step workout Cathe just finished...and then orderd Cardio Hits. I wanted a well-rounded cardio library with some "easier" stuff for light days to match against the hard workouts (Imax 2, Step Blast, Lowmax, etc.) I already have. I've also got another purchase in the works, too. Somebody stop me!
