Jon,
I'm taking it you haven't played the new Cal?
In terms of better or worse I'm not sure how to really answer that question. SFGC is arguably the model golf course when it comes to strategic bunkering. The aesthetics of the bunkering at SF and Cal are both stunning.
There are obviously bunkers at Cal that aren't directly in play, but they do serve a purpose when it comes to alignment and visual trickery. Also, the strategic value of the bunkers is exponentially better than the previous course.
1. After a good drive, the right green side bunker wrecks havoc if going for the green in two. After a poor drive, or just the shorter player, the bunker complex at about 120 from the green play a HUGE role on the lay up. You DON'T want to be in those bunkers..
2. You would think the carry bunkers on the left hill aren't really that important, but they do serve as a an aiming point. I have also seen a handful of people end up in them after poor drives. The rest of the fairway bunkers are also very relevant, especially the cross bunker about 150 out, and the three bunkers about 40-70 yards short. Since the hole is over 450, the bunkers get much more action on second shots than you would anticipate.
Ok... I was going to go hole by hole but it is going to be a bit tedious and I don't have time for that today.
Either way, the bunkering from 100 yards and in is unbelievable and very strategic. The fairway bunkering on 3, 5, 7, 10, 13, 14, 15, and 17 is all well placed and influences play.
The green complexes are AWESOME on 1,3,5,6,7,6,9,10,11,12,13,14,15 (SOO Cool), 16,17, and 18... I guess that was kind of stupid because it was pretty much every hole but the bunkers is just awesome around the greens.
Even on holes with "bunkers not in play" such as 1, 9, 10, 11, 14 (in play on 13), and 17 the play the vital role of providing a target for alignment.
Oh... and all these bunkers that "aren't in play", I have seen people in pretty much every single one of them.
I tough to really discuss the differences between the bunkering at Cal and SF through typing, but they are both EXTREMELY well done and influence play to a great extent. With the UNBELIEVABLE WIDTH at both courses, the bunkers have to be well placed to influence play.
That isn't the best written analysis but I hope it says something about the bunkering.;
