Mark,
I understand what Mr. Nicklaus is trying to do, but the furrowed bunkers don't create a hazard that is consistent for the entire field, the lies you get are too random (luck). A water hazard is a water hazard, most of the time the ball is unplayable. Sure you can get lucky some times and have a shot (Fred Couples at Augusta- and I will say for the third time that I understand that luck is part of the game, it should be, and certainly is one of the things that makes the game what it is), but the result with a water hazard is more consistent.
Mark you also mentioned in an earlier post that bunkers in the UK, for the most part, are more penal and therefore more of a hazard. Having only made one fantastic trip to Scotland and therefore having very limited experience, I would agree that was certainly the case on the courses we played. But compared to courses in the U.S., especially the courses on the PGA Tour, there are far fewer bunkers on many UK courses and therefore they are easier to avoid (thru course management). It seems proper that the penalty should be higher there because perhaps it requires a bigger mistake to get in a bunker. This isn't the case on most bunker-happy US courses.
I would also like to say I am speaking directly to courses being used for professional golf tournaments, although my feelings are pretty much the same for any course set-up. These guys/gals are playing golf for their living, it's a business. I believe every attempt should be made to level the playing field (I know I'm going to get hammered for that), so that it is ultimately the player's skill that determines the end result (knowing luck will be a part of it regardless).
Ryan,
I'm not saying they are and thankfully courses aren't set up that way every week. However, I do believe that rough and narrow fairways provide a more consistent challenge than unmaintained or furrowed bunkers. There results are less random.
Matt,
You bring up an interesting point with the softer sand. I personally think that is a better way to go because the bunker becomes more difficult while remaining fairly consistent for everyone.
