I think for a full workout, you will want to look at the Pyramid Series. She does drop sets here and there in STS and other workouts, but Pyramid comes the closest for a full body drop set workout. (I can't remember because I usually do the workout as filmed, but I believe that the premixes available are you can do it pyramid up [one premix] and pyramid down [another premix]. Probably pyramid down would be the one you would be interested in for drop sets).
