EDGEWATER, N.J. — Ducks quack, dogs bark, cab drivers honk and golfers slice. Among the basic truths of the planet: 80 percent of golfers cannot hit their tee shots where they aim.

But what if there were a golf ball that went only straight?

“That would be a miracle,” Dion Cooper, 26, of Brooklyn, said as he swatted balls last week at the Edgewater Golf Range in northern New Jersey.

Mr. Cooper was hitting his driver toward the Manhattan skyline, the balls tailing off in the familiar arc of the classic golf slice. Then he was handed the new Polara golf ball and took a healthy swat.

“Straight as an arrow,” he yelped with a mix of awe and surprise. For the next five minutes, he rarely hit a ball crooked.
