The PGA Tour season pushes on this week with the RBC Heritage at Harbour Town Golf Links, about a three-hour drive southeast from Augusta National.

While Harbour Town is one of the most picturesque stops of the year, it also packs quite the punch with some of the Tour's smallest greens and tightest fairways.

 "It's a classic golf course. It's one you have to really manage your game around," said Pro V1x loyalist Luke Donald. "You have to think your way around very well. ... It's going to be tough to hit a lot of greens this week.  And because of that you need a good short game."

An overwhelming majority of players this week are relying on Titleist golf balls to successfully navigate them to the finish line, marked by the famous view of the Harbour Town Lighthouse behind the 18th green.

A total of 90 players in the field are playing Titleist Pro V1 and Pro V1x golf balls, more than six times the nearest competitor with 14 and more than all competitors combined. Titleist is also first in iron sets (34); sand, lob and approach wedges (127); and putters (58).
