Brent, If the equipment were such that a killed drive from a big hitter would generally not break 280 yards, do you really suppose there would still be a perceived need for 500+ yard par fours?

JK,
I am not here to keep architects working. Their bests interests don't always line up with what is good for the game or its courses.

Andy, the jump in distance has come for those with higher swing speeds. Not necessarily just tour players or even good players, but ones that can generate enough club head speed to take advantage of the new equipment relative to the old.
I don't know what that swing speed is, but I'd guess it is somewhere in the mid to high 90s. I once tested a Pro V1x vs. a Balata hit by a low handicap golfer with a swing speed in the mid to low 90s (25 drives with each on launch monitor, threw out worst five for each) and he hit the Balata a few yards longer on average. Don't know if this would have been the same with Pro V1 or not, but if he could hit the ProV1 longer I doubt it would be by much.
Other than with these golfers, I would tend to agree with you that most golfers have not gained much distance. In fact I think that is a large part of the problem architecture-wise.
Unless you want to ignore this group of golfers, it has become a real problem to fit everyone on the same course. It is no longer just a matter of having a couple of tees. A course can easily be way to long for most is still way to short for some. (When I say way to short I am thinking of maintaining the architectural relevance of features, strategies, green sizes, angles, etc.) So it makes quality architecture that much more difficult. We don't all fit on the same courses.
Sean seems to think we should just not worry about the longer hitters, and keep the courses as they are for the rest of us. I nice idea, but it ain't going to happen, and even if it could happen, I am not sure it is the best approach. One of the beauties of the game and the marks of great design is that golf courses could be enjoyed by a variety of skill levels. Do we really want to do away with that? Why would we if we could fix the problem by fixing the ball?
