I agree with GolfinSC. Without competition from different manufacturers, technology would lag behind. Let them all compete with each other to develop the next best ball. If everyone wants to use the Pro V1 series, they're all more than welcome to... but it's more of a case of which ball manufacturer is paying what player what amount of money to hit their ball during a tournament. Also, if you choose to go the route of forcing everyone to play a certain ball, where do you stop? Do you force them all to use the same driver? Same putter? It is a slippery slope effect that would never end. Next they'd all be wearing the same red Nike shirt, same tan khaki pants, same black Nike hat, same black Nike shoes, same clubs, and they'd all have to be called Tiger, because the tournament is the Tiger-Nike Classic.
