Would agree with Bill B.
The technology (ball & equipment) plus possibly stronger golfers have affected many, many courses.
In the future, the grandkids will tire of hitting driver 9 iron or wedge to every par 4 and move on to another course, or sport. Just go watch any high school or college match.
Money spent on existing non-tour courses is much about adding tees, movings bunkers, moving greens in some cases, buying more land, watering and fertilizing more grounds. And, new courses are often greater than 7500 yards.
And for what ? So some ball manufacturers can continue and never have to make adjustments.
Still maintain the ball is the method to reign back yardages. Either by spin rates, gross weight, or some other method the 'experts' can formulate.
The manufacturers spend a lot of money on R&D and until R&D budget is zero, the ball will continue to be improved. Also wish the USGA club head speed for testing was higher.
The manufacturers spent on R&D, marketing, manufacturing, packaging, shipping, mark up for a profit, etc. The retailers can sell a very reasonable ball (like TopFiltes Feel, etc. not much different in materials, etc. than Titleist) for less than $1 a piece.
And new courses have to be built 7500 yards and old courses have to add new tees, move bunkers, etc. ?
The USGA doesn't manufacture anything, and they will be caught short again.
None of the manufacturers, in my opinion, will share developments with the USGA. The manufacturers will continue, by R&D, to inch ahead and move forward.
R&D is not all about making the white paint last longer or look whiter than white.
>> In 1974, the big 1.68 ball was required for the Open. Revisions in effect in 1990, outlawed the 1.62 small ball altogether.
