Yes, more step!!!! My current rotation is cardio, total body weights, cardio, upper body, cardio, lower body, cardio, circuit training, then interval training and start it over again. So you see, I go through cardio a lot quicker. I definately vote for rhythmic step 2, step blast 2 etc. I'll say that it should be broken down approx. 15, 15, 15 plus a 15 minute step challenge plus approx 15 minutes divided between warm-up, cool down and stretch. I liked rhythmic step, but I kind of would like a little longer time frame for each segment. It seemed that about the time I really learned the routine and got into it, then it went on to the next one. Maybe repeat each segment a couple times more. In the interest of time, I don't like my cardio to go much over 70 minutes. I like 90's dance music background-like "shape your body", "pump up the jam", "Ooh baby, baby",(I might not have the titles right, but atleast those lyrics are in the songs). I always blast those songs on when I am on the treadmill.
I can't remember the exact breakdown of rhythmic step, but if it takes too long to "build" each segment into 15 minute segments, then do 2-20 minute segments with a 15 minute step challenge then 15 minutes divided between warm-up, cool down and stretch.
