If you learned to clean from Broz, you know how to clean. We use the power clean in our programs because we are not making Olympic weightlifters, but rather teaching novices an explosive lift that can be used in a general strength and conditioning program, and the power clean is easier to teach and learn. We'd rather see you pull the bar over a longer ROM, instead of just pulling it high enough to get under. Most importantly, we'd much rather you learned to squat using hip drive, and most novices have a hard time separating the movement patterns of the squat we teach and the front squat part of the clean. We'd rather have the squat learned to the point that its movement pattern can be kept separated from the front squat, and this usually takes several weeks. So learning the clean would interfere with our novice's ability to squat correctly early in the program. This is discussed in the book.
