To be honest I am not a fan of JKD proposals. The rough edged bunkers are more suited to courses like Pinehurst.
Augusta is all about clean lines and precision.
Imagine if the club reverted the 7th to what Mac had originally intended. For me the players found it more difficult to chip from tight lies around the greens than play out of the bunkers. This would make it easier for the members but harder for the pros.
Tiger had a great article in the Times before the Masters - he said he would shorten the course, remove a number of trees and widen the fairways and take out a few bunkers. He mentioned that the 5th new fairway bunkers were ridiculous as well as bunkers at 330 yards away from the tee on the par 5s where it should shorter to enable players to carry it with more risky drives.
Boy I do miss those choccy drop mounds on 15 that hole is one dimensional off the tee nowadays. Great 2nd shot by Sergio though!
