Mark,
"the old design" (on 13 and 15) you refer to was only a recent phenomena brought on by technology's march.
Gene Sarazen made a heroic and desperate choice to go for 15 in 1935 with a bounce up wood shot.
Had he holed out with a wedge or 9 iron for a double eagle, it would've been an incredibly timely shot, but it hardly would've been a heroic choice.
Plenty of players have laid up or faced 1 irons and woods to 13 and 15, making the decision to go for it quite bold off a downhill or sidehill lie.
In recent years, the same lie with a middle or short iron eliminated the decision.
As you state, the players felt "compelled to" go for 13 and 15 in the past decade.
Doesn't that make them par 4's of the penal school, rather than the truly great STRATEGIC par 5's they were intended to be?
Shouldn't Tiger Woods with a huge, accurate drive have an option not available to Zach Johnson on a well built strategic par five?
If they both can successfully consistently go for it, where's the choice and strategy?
The holes once again involve a strategic approach involving choices and playing to one's strengths, as they did when originally designed.
The weather leading up to the tournament and during the tournament were the reason for the scoring issues.
I'd say they got the mix just about right, given that they got similar winning scores under similar conditions in 1954, 1956, and 1967.
It was a great tournament.
Augusta is a 9.
If they eliminated 10-20 of the new trees on 7 and particularly 11, and limbed up a couple more (which don't affect strategy but rather inhibit recovery)
and eliminated the rough (which just looks messy and keeps ball from rolling off)
it would again be a 10.
