Speaking for myself, I feel that if somebody breaks Mosconi's high run record having used a jump cue even once, the run should not go into the record books. If you butcher the shape to the point that you have no shot with your regular playing cue, you return to the chair. That's the way it always was and the way it ought to be.
For the record, as Schmidt's jump in the quarterfinal against Harriman was executed with a full cue, it was fine by me.
