Mark,
I just purchased Bill Starr's " The Strongest Shall Survive" and read his section on the power clean. It seems interesting that his teaching of the PC encourages an arm pull/ upright row to rack the clean. By the time Bill was teaching you the lifts was he still teaching the PC this way? If so, at what point did you deviate to your own method and cues to teach the power clean?
I've finally removed arm pull from my own cleans and am finally progressing on the PC without beating myself up and just find it interesting how much different Bill taught the lift.
