At the risk of getting flamed, I'll say:
In general, I view drop zones as a cop out. I understand that they can have a positive impact pace of play, but they never add challenge to a hole. Literally, they improve prospects for a player who hits a poor shot.
To argue that the drop zone on 13 was in any way intended to speed up play is ridiculous. If pace of play were a concern at all, the 5+ hour rounds played by twosomes on Sunday wouldn't have been permitted.
