The Bridgestone Tour b330-s is designed for golfers seeking exceptional, consistent performance while achieving incredible distance and optimal greenside control. The tour-caliber b330-s is a softer feeling golf ball that spins more and will have higher trajectory than the Bridgestone B330. If you have a swing speed over 100-112 mph or if you have a lower trajectory and feel like your shots are not spinning enough, this is the ball for you. It will have a slightly softer feel off of the Club face, a higher flight trajectory, and more spin on shorter wedge shots than the B330.
