The Bridgestone B330 is designed for golfers seeking exceptional, consistent performance while achieving incredible distance and optimal greenside control. The B330 is a harder feeling, Tour-caliber golf ball that spins less and will have a lower trajectory than the Bridgestone B330-S. If you have a swing speed over 105 mph or if you have a high trajectory and feel like you are losing distance because the ball is ballooning on you, this is the ball you need to play. The Tour B330 has a lower flight trajectory and less spin on shorter wedge shots than the B330-S.
