Tom, I love classic courses, even though I have had a limited opportunity to play them. Now that I live in the classic course deprived west, I have even less opportunity.
However, the USGA has to balance their approach to this issue because there are more entities involved than members and lovers of classic courses.
A large majority of golfers, whether they play classic courses or cow pasture muni's enjoy the benefits of new technology. For them the game is more fun and it's easier.
My thinking on this issue is the USGA can gather data,, and continue to regulate equipment in a way that keeps golf fun and easy for the majority of golfers.
You, as a member of a classic course can determine how these changes in equipment impact your course and your membership and act accordingly.
New courses do not need to be 7600 yards for the tips. That is pure ego, either the developers or the architects'. Yardage alone does not make a course a challenge. Besides, who is going to play from those back tees and how often? I'll bet the black tees at the Old Works in Anaconda are used for less than 10 rounds aweek. The land that is saved by NOT building multiple tees, or adding yardage could be better served by adding features...interesting green complexes, fairway options, etc.
Whether the course is 6000 yards or 7600 yards is of no concern to the USGA. Nor should it be. Perhaps, when long hitting professionals or long hititng "anyone elses" are the everyday golfer on our courses, they should act, but until then, I favor their current approach to regulating equipment.
