There has been a lot of discussion that the current ball goes too far, is slowing down the game and forcing courses to become longer and more costly while rendering many classic courses "obsolete". In addition, in defending the current ball, many have stated a reduced ball will not only affect the longest players, but will make the game harder for the rest of us.
I believe much of the complaint about the ball is true. Longer, more penal courses take longer to play. TPC Sawgrass is a prime example. Longer courses mean more land and maintenance costs.
Still, I have to also believe a new ball can be designed to reduce the flight for faster clubhead speeds while having almost no effect on slower swings. In essence, a ball that the faster you swing, the less ball speed is achieved. Perhaps, this is the way to solve the problems with the longer balls of today.
